Help please

I learned today from YouTube 420 scene, ( pretty smart dude ) keep them lights 24". But for sure its some type of nute deffincey as in to much and locked up or missing something like cal mag or epsom salt. If your using FFOF I would say to much nutes. I it was me using FFOF like I'm using, I would let it dry out and water only next 3 cycles pH at 5.9. I hope it all works out. I'm growing AK myself for first time.

It's not your garden plant in greenhouse, you have to water when pot us dry, that's why fluctuations in pH and all issues, let her dry totally and give two only phed water cycles - wet/dry/wet/dry. She should recover easy. It's very important to follow good pH, make sure your water is dehlorinated and you give it when plants need... All the best !

I’d be worried about that 7.5 pH you got from the soil. Also - fox farms trio is ridiculously over dosed so I wouldn’t be surprised if you were locking out nutrients with too much feed. But it depends how much of the grow big you’re putting in. Your diary has no info on that
