I think I finally have things dialed in:
A few days back I noticed some pH stress in my plants so I bumped up the pH of my water to help compensate. I knew my TDS was high as well but since it's been high I have no way of knowing exactly what nutrient combination was remaining in the soil so I decided to feed at a low rate to compensate for any imbalance. Looking at my plants the next day I noticed a huge improvement.
During the watering I decided to test the pH, TDS and EC between additions of the Roots Excelurator, Megacrop, and even the GH pH down solution. I was surprised to observe how much the pH down solution adds to the TDS. Looking back I believe that I may have accidently adjusted down the pH of the distilled water addition from my previous post. I'm not used to using distilled or RO water and I was surprised at how wildly the pH changed when I attempted to adjust. That's a solid mental note for the future.
Now that we are back on track and things are looking good, let's talk about that SCROG screen. That thing is slick. It was super easy to install and weave the grid. The squares are spaced at 3" so we should be able to use that as a reference to the canopy area of each plant as things progress. The screen is set at 6" above the rim of my containers and it's going to be a tight fit to get under there and put in work. I wish the zipper on my tent went flush with the floor so when I have to crawl under everything I can fit easier. From the ground to the net is 19". The orange string is kind of cool. I only chose the color because it was the cheapest but I do like the look of it all set up. The supplies I used to build the SCROG screen were listed in the previous post.
I only have a couple more days to determine how I will arrange the plants in the tent. I'm thinking how they are in this set of pictures might be best. Having the plants closer to the back then guiding them towards the opening makes sense right now but I've also considered running them left to right. Or maybe start one towards the back on the left and one in the front right and have them offset like that? Do you all have any opinions on this?

Welcome to the beginning of Veg week 5. Here's the latest numbers:
Not a lot going on since my last post. I thought the plants would have consumed more of the nutrients in the soil and brought down the TDS by now but it seems like we are still running a bit high. I would have just run water tonight had I known. The next watering will be just straight water and I have a note in my spreadsheet to remind me.
The leaves on the plants feel papery and are still showing a bit of stress. The plants are still growing but not as fast as I anticipated considering they are sativa dom. Maybe they'll show up in the stretch? Right now I've got a couple of bushes but I know they will start to reach out soon.
We have had some cold and I've been adjusting the temperature and humidity to stay within a good VPD range. Everything seems to be pretty rock steady with temp and humidity.
If anyone out there on the farm things I'm missing something please let me know. Thanks!

Still rollin' in Veg Week 5:
Plants are growing, slowly but surely, and tucking has commenced. Leaves are still papery feeling but I'm seeing signs of improvement. I was definitely overwatering before when trying to correct for the pH and over fert measurements. I probably would have been better just going hands off as the overwatering caused more of a problem than the others. I raised the lights and backed off the intensity slightly to allow the plants to recover a bit. The SE7000 is an absolute monster of a light, especially in a 4x4.
As I mentioned previously, one of the main points of focus for this grow is developing a strong root system in these bags. I decided to implement a brilliant yet simplistic technique I discovered here on the farm. I punched a couple of small holes in the bottom of my bags so that I could drive in the moisture meter directly in the target area. I immediately noticed a difference in the readings. Going from top down it appeared my soil was dry but when I stick the meter horizontally in the bottom there was clearly moisture there. This led me to an extra day between waterings and because of that I decided to feed again even though I said I wasn't going to.
I didn't take runoff readings this time around for a couple of reasons. First, the plants are just reaching the net and I would need to move them around a lot to get to the run off. I would rather them become a little more established in the trellis before moving them around. Second, because the previous runoff readings were looking much better, and now I have more accurate moisture measurements and wanted to prevent additional overwatering, I only watered to sufficiency and didn't have much runoff to measure!
This being my first grow journal here at the farm has been kind of humbling for me. I don't typically have this many issues. I am running a brand new light, different HVAC arrangement, a new strain, intensive scrogging for the first time, and focusing (probably way too much) on increasing the accuracy of my environmental conditions, nutrient and water delivery. I'm going to keep taking notes and do my best to turn this thing into something respectable.

That's a pretty slick hack there with the moisture meter.
You try letting them get a little warmed up? I like my veggers with an air temp in the mid to high 80s to get their metabolism up and breathing a little heavier. The leaves will remain cool with a breeze but that warmth in the root zone can help kick 'em into gear.

After getting the IR temp gun I realized I had some room in the higher temp area so I bumped them up a bit. I will take your advice and step it up a little further, maybe all the way to 88F and take another reading at the leaf surface? The plants seem to be around 5F or so cooler than ambient. If I see progress in a couple of days I'll start raising the light intensity again as well. Thanks for the tip!That's a pretty slick hack there with the moisture meter.

Yeah it's a little crazy how warm a room can get but the plants stay cool. I've had my room in the 90s and surface temps of leaves is still in the mid 70s.
It is a little hard to tell on my end though because overly intense light and cold roots almost have the same effect on looks of a plant but seeing that 81 being your high mark my move would be let 'em warm up. They'll tell you if it was a good move usually in a day or two. Good luck Buddy!

Full on into week 6, here is what I'm working with:
The plants are vegging and putting on nodes and I'm tucking away. I'll need to get under the canopy soon and do some heavy defoliating. I'm guessing that will be around this time next week.
Allowing the ambient temperature to increase to around 88F has resulted in a noticeable rebound in plant growth. That was the right call @AnimalHouse, I appreciate the advice.
I've decided my method for guesstimating the PPFD is probably trash and I'll be investing in a PAR meter soon so that I can better track my photon delivery with this new light. Last night I dialed the light back a bit after noticing some light stress and the plants seem a bit more comfortable today. The stress was also partially due to an increase in temperature. We've had warmer weather the past couple of days and I caught the temps jumping to around 92-93F temporarily. I still can't get over how much more powerful this light is compared to my old lights. When I do get a PAR meter I'll be super interested to see what kind of intensity those oldies were delivering.
I gave the plants a day off on nutrients. I'm not seeing any new signs of deficiencies or toxicities, mainly just the light stress. The soil was pretty dry yesterday and they took the full 3 gallons with almost no runoff. After that much water the moisture meter was giving a comfortable reading so that helped to resist overwatering. Punching a hole at the bottom of my bags helped out a lot.
Plant 2 continues to struggle but looks to be improving. She's still growing but is producing significantly less vegetation. Going forward, assume all measurements are related to plants 1 and 3 only. I'll be treating plant 2 as it's own thing as the different container size and type is having an impact on watering frequency and nutrition.
Now that the plants are filling in I'm thinking the intensive scrogging process would be much more efficient with 4 plants in 3 gallon containers. I might try that on my next run.

I've been busy lately, but not too busy to get some numbers:
We are now into week 7 of veg and the plants have taken off. I'm pretty happy with their progress but I likely set myself back a week with all of the early issues. This is a bumper crop for me so I've got a little extra time for things to develop out all the way.
A couple of days ago I noticed the plants were looking a little stressed so I dimmed the lights a bit and hit them with the Superthrive. They all responded well to the change.
When I checked on the plants this morning they seemed a little pale like they wanted a little more N so I did a foliar feed with urea mixed to 1.5% and sprayed just before the lights came on this evening. They took it up quick and the plants are looking pretty happy now.
Other than a bunch of tucking, there hasn't been a lot of work in the garden but I've been busy working all around it. Some of you might have seen my thread from last week where I found a crazy deal on a bunch of new equipment. The new air pump puts my old one to shame. I got a really nice Hanna pH/TDS/EC meter, new filters and other hvac parts, loads of 1020 trays and 72s and so much more. Soon I'll have to climb under the screen and defoliate hard but for now I'll let them keep doing their thing.

I had planned for 8 weeks of veg and I'm thinking I'm on track for that. I'm going to get underneath the canopy this weekend and thin them out really well. It's a jungle down under the net. Up to this point I've only defoliated a few fan leaves here and there. I haven't even topped the two bigger plants which is fun. Once I have things all cleaned up down below I'll give the plants a couple of days to recover then I'll get started with the big show.

I can't believe it's veg week 8 already.
The day after applying the urea foliar feed I noticed some fried tips on several leaves of every plant. Damage wasn't too bad but I'll note for next time that I need to use a more dilute solution, maybe around 0.5-1% max. Given the runoff TDS from the watering this week I'm thinking the plants were probably just hungry and a regular feeding would have been sufficient. I did the foliar application because I was still thinking I was running a little high on TDS in the soil. I'm glad the feeding schedule is back to normal, that makes my life a lot easier.
I got under the plants and did a heavy defoliation. I cleaned almost everything below the screen and the plants haven't skipped a beat. I did dim the lights down slightly for a couple days to help reduce any potential stress but now they are back up in preparation for the flip to flower.
The screen is starting to fill out. I'll keep tucking at least a week into flower. I have more room than the pictures might suggest so I'm not worried about space. I still have topping and super cropping options for any tight space I might run into. The plants are still easy to manipulate for tucking.
I've been busy getting my back yard garden ready for planting. I decided to put together some drip to make watering easier and also to get more consistent watering. We have a very light sandy soil that has a tendency to dry out quickly and it eats organic material like nothing. I amend with a recipe I made using a soil test and calculations I derived from the book The Intelligent Gardener by Steve Solomon. It produced some great results in the past and I'm looking forward to some nutrient dense, great tasting food to come out of the garden this year.

The day after applying the urea foliar feed I noticed some fried tips on several leaves of every plant. Damage wasn't too bad but I'll note for next time that I need to use a more dilute solution, maybe around 0.5-1% max. Given the runoff TDS from the watering this week I'm thinking the plants were probably just hungry and a regular feeding would have been sufficient. I did the foliar application because I was still thinking I was running a little high on TDS in the soil. I'm glad the feeding schedule is back to normal, that makes my life a lot easier.
I got under the plants and did a heavy defoliation. I cleaned almost everything below the screen and the plants haven't skipped a beat. I did dim the lights down slightly for a couple days to help reduce any potential stress but now they are back up in preparation for the flip to flower.
The screen is starting to fill out. I'll keep tucking at least a week into flower. I have more room than the pictures might suggest so I'm not worried about space. I still have topping and super cropping options for any tight space I might run into. The plants are still easy to manipulate for tucking.
I've been busy getting my back yard garden ready for planting. I decided to put together some drip to make watering easier and also to get more consistent watering. We have a very light sandy soil that has a tendency to dry out quickly and it eats organic material like nothing. I amend with a recipe I made using a soil test and calculations I derived from the book The Intelligent Gardener by Steve Solomon. It produced some great results in the past and I'm looking forward to some nutrient dense, great tasting food to come out of the garden this year.

I did a thing but first, the numbers:
Yesterday was the flip. Plants looked really healthy and are adjusting really well to a rapid increase in light intensity. Migro released a video recently that describes a linear relationship between modern LED lighting and dimming. Now I'm thinking my edumacated guestimate of PAR might have been on par. I don't have a par meter to measure using my personal setup so youtube PAR testing reviews are what I referenced for my calculations. Taking notes with pictures has really helped keep track of things. I'll just keep doing what I'm doing for now.
The plants were looking a little hungry yesterday so I bumped up the nutrients a bit. Other than that, no issues.
The screen is starting to fill up. I still have at least a week of scrogging before I let them reach for the sun and start to get fat. I'm pretty excited to see what kind of yield this will return. I've filled up some tents and rooms before but never like this. If anything, it's a fun technique.
One last thing of interest is yesterday I bought a new window AC for the room the tent is in. It's an LG 12K btu model that really pumps out cold air. It has a dry function and initially I thought I might be able to replace my big dehumidifier but on the ac it's more tied to temperature than humidity. There isn't even a humidity display on the unit. I only paid $200 for it new in the box and I'm pretty happy so far. FYI I am replacing a 12k btu portable unit that I had for a couple of years. It was bulky and I hated how much water I had to move due to not having a good place to run a hose. Not to mention they just aren't as efficient as window units that recycle the indoor air vs pumping the hot air out of an exhaust.
One last thing is over the past couple of days I've seen my CO2 levels spike over 1100 ppm. That's without me being in the room. I'm not sure what caused that? It's not the ac because it's not happening today, levels are actually pretty low today. I'm seeing the high measurements on my inkbird outside of my tent and also the inkbird remote monitor so it's probably not that. I dono?

Filling up nicely there. New AC unit should be a nice quality of life upgrade.

It certainly changed my previous HVAC plan, in a good way. I'm now treating the room around the tent as a lung room where before I was doing all kinds of different things based on daily weather conditions indoors and outdoors. Life is a lot simpler now.
I was concerned at first about the amp draw so I went around the room with my kill a watt meter and tested each component of my room individually and made notes of it. That led to me redistributing my current consumption around the room a little more evenly (originally had the light in same outlet as AC). The result of that was a much better cable malmanagement layout, so I knocked several birds down with the addition of the AC.

Thats sort of what I've been doing re the lung room thing. We got lucky with this house, the basement my grow room is in was finished and has it's own hvac. Ambient has been a big component of maintaining my grow space climate with relatively small amount of additional equipment running.
