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.
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.
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.

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 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.Looking good when ya flippin ? Gonna be a full house! Lol

Thanks buddy, I appreciate it.looking great!
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.Filling up nicely there. New AC unit should be a nice quality of life upgrade.
