Do you think this will finish okay?

[freezeland2]

I knew that... kinda. This is where my lack of experience matters. I should have seen that and done something about it.


I totally agree. I've been thinking as we've worked through this that next time I'm going to make sure the plants are healthy before I flip. They didn't look bad, though. I have been scanning through the pictures and the problem clearly began after the flip.

I had been wondering if the tip burn could have been because they weren't transpiring as they should. I've had trouble with the AC Infinity controller. It it's on "auto" in the phone app, it doesn't work. It has to be left on one of the active ports or it shuts everything off in an unpredictable manner. I have reported the problem. The Ink Bird controllers have since become my favorite.

Here's the latest reading from a different sensor.

I have a bit of experience with the ac controllers. I am going to ask a couple basic questions and don’t want to offend. Have you verified you have connectivity between the app and the controller? Also have you checked to be sure you have current version of the app installed? You can do that by going to the App Store and compare the version number there and the version number on the phones app. Also check for firmware version on the controller. You can also check that in the app. I know there is a recent firmware update out there right now for the 69.

After checking all that you can try changing ports on the controller. That will rule out the controller port or point to a possible issue with the device that is plugged in to the port. Make sure all connectors are firmly seated in the controller. If you are using the ac infinity extension between the device and controller try removing it. Do you have a spare UIS cable to replace the current cable? A screen shot of your auto settings would help to assist further.

The soil pH is about 5

likely salts buildup in soil

You got your watering practices locked in?

I hope so. I check the soil moisture several times a day and water when it's low.

Do you have any pictures from before you flipped?

Here's the best one. It was taken three days before the flip.

When using FF nutes I found that using calmag during all of veg is best way to go as their line dosent have enough of it ... cal mag is not really wanted to be used during flower phase it inhibits the phosporous and potassium uptake if im not mistaken...

As for the now... ya using calmag will help for sure...can always cut back on the base nutes as well

Thanks. I'll keep that in mind for my next grow, and yes, it sounds like Cal-Mag is on the menu.

likely salts buildup in soil

I thought salts were caustic and thus raised pH.

all soluble nutrients, such as nitrate, ammonium, potassium, calcium, magnesium, chloride, sodium and sulfate, contribute to the soluble salt content of the media.
fox farm tiger bloom ingredients: calcium nitrate, magnesium nitrate, ammonium nitrate, ammonium phosphate, potassium phosphate, potassium nitrate, earthworm castings, Norwegian kelp, iron EDTA, zinc EDTA, manganese EDTA, copper EDTA, chelating agent, disodium ethylenediamine tetra acetate (EDTA), sodium borate and sodium molybdate.

foxfarm grow big ingredients: ammonium sulfate, ammonium phosphate, urea, blood meal, potassium nitrate, potassium sulfate, earthworm castings, Norwegian kelp, iron EDTA, zinc EDTA, manganese EDTA, copper EDTA, chelating agent, disodium ethylenediamine tetra acetate (EDTA), sodium borate and sodium molybdate.

ammonium nitrate, ammonium phosphate are the ones accumulated in the soil causing lower ph

There's just so many factors almost seems impossible to know exactly what's going on. My grow is the same. I've got some yellowing and brown spots but I'm just gonna have to live with it. It usually turns out OK

Thanks so much for the very well-written help. I really shouldn't have complained. There isn't a hardware problem and the firmware is up to date. I like how it calculates VPD. The software is just a little quirky, making it hard to trust it.

I goofed on that question about salts. Too high, I guess. I confused the chemistry. A salt is created when an acid combines with with a base. Salts can be either acidic or basic or neutral.

you were thinking of sodium (Na) on its own?
sodium is the most common alkali metal and the sixth most abundant element on earth, comprising 2.8 percent of earth’s crust.

 

[BigBlonde]

Nope. I just made a mistake when I wrote the question. Though I knew better from chemistry courses I took long ago, I was thinking salts were basic, which is incorrect, of course. Your comments are very helpful and have me thinking--and there's always the next grow.

My plants' problem(s) remain the challenge at hand: What can I do with what I have to improve the situation? I didn't post another picture today because there's very little observable change. Adjusting the climate may be helping. We haven't had a full-day cycle yet, so it may be too soon to tell. After 2 1/2 hours into today's light time, the left plant is looking a little greener, but the right plant may be slightly worse. I suspect many of the yellowed leaves won't recover, no matter what I do.

have you got the soil ph sorted out

 

[BigBlonde]

have you got the soil ph sorted out

No, but I've been thinking about it. Evidently, I need an amendment that will raise the pH, but I don't know what that would be, or worse, whether I could get something in time to matter. We have baking soda (sodium bicarbonate), but even if that would work, I wouldn't know how to mix it.

 

[GreenGalaxyFarm]

at this point im probably gonna jump on the 'try to ride it out' wagon as best you can. next grow lets get your plants into some real soil a natural buffer?

 

[GNick55]

i’ve gave you advice and others have too..

I think that's best. I always look forward to the next grow.

I have a small tent due to arrive tomorrow and plan to use it to start the next grow while these are finishing. I already have FF Ocean Forest soil and some rice hulls. I need to order some perlite. I'm also thinking of using organic nutrients as much as possible.

perlite sucks imo just turns to dust over time, hydroton is much better for aeration and hosts microbial activity.
organic ferts are great for soil! theres more that goes into a supersoil tho, but well done on the rice hulls so far, im sure you know its purpose it to add silica.

 

[BigBlonde]

i’ve gave you advice and others have too..

Yes, you did. Are you angry? If so, what did I do wrong? I sincerely appreciate everyone's help.

We didn't discuss adjusting the low soil pH, and I doubt there's much that can be done about that at this point. Today's posts have mostly been follow-up on what had been discussed previously and doing some thinking about the next grow. I'll try to do better then.

I'm pretty sure I'm following most of the advice. I can't water in nutrients yet. I adjusted the climate controls. Here's what it looks like now. The humidity is up and the VPD looks good. I dropped the temperature down two degrees, too. I noticed that the humidifier isn't running, so the plants must be transpiring better.

I have stayed away from perlite so far. I believe I need to improve drainage, though, so that's why I'm considering using it. I understand the role of silica and I also understand that rice hulls work well for drainage. They're also organic. I just think I either need to use more next time or come up with another or an additional method. I do believe drainage has also been a problem with this grow. In my other gardening, I've used the hügelkultur method with success. I also used it in my previous grow, but then I heard that it wasn't recommended for cannabis grown in containers. I'm not sure about that, though.

I'll look into hydroton. I have not heard of it.
