are you running organic? is there anyway to bring your ph down to 6.5, what's your temps?

I can bring it down with some citric acid. I was going off the notion I didn't need to due to the soils buffers. Its looking more and more like thats the issue.

the lime will pull it up to 7, its more alkaline , did your soil already contain lime or buffers? too much lime and its difficult to get below 7, I use 1/4cup per 5 gal
depending on how finely ground depends on how it releases , I did this to a mix of ocean forest and ended up with cal def, even though the dolomite is a calmag source, the pH would never drop even with 5.5 going in

Regardless of new soil the plants look nitrogen deficient for some reason. I don't know soil, but I'm assuming it's amended with nutrients. I was going to suggest it looked dry until I saw you mention saying they've been watered correctly.
You normally pH but haven't been because the soil has dolomite lime in it? Or that was your thinking? If that's the case I'd get back to pHing the water each time.

ok then I'd trust the content of the soil , try some ph down , the lime will prevent it dipping into the low 6s but it will never go lower because you need a stronger acid

Out of curiosity how far away is the SF2000 right now and dimmed or full power?

Yea thats the factor thats different. Im gonna get back to pHing the water and see how that does.

I think transplanting and immediately topping them might be a factor. The transition to new soil plus the shock of topping, they may not have spread their roots enough yet to make use of the new soil, and problems have their own momentum in soil. Problem is they're yellow enough that if I'm wrong (and I very well might be) you're not really in a place where "do nothing" would be a good plan.

Absolutely. My outdoor experience has applications to this that will definitely help. But just like anything else in this world you don't know what you dont know.
I was trying to do this whole no chemical thing hence why I didn't pH. But Its totally not my forte.
I will get it figured out.

tbh I've never had a plant go pale after topping or transplant, they mostly wilt (transplant) or stall vert growth for a bit (top)

And there are about 8 messages there while I'm typing, lol. The phing of the water is the only other thing that's changed, so...Yeah.
Do that.

Yeah, but they weren't in the early stages of N def when you did it were they?
