I have a problem, my plant especially top laier is getting lime green yellow, leave stems are getting purple, and have some small dots on the leaves, runoff PH is 6.9, i'm waterig with 6.0 PH, PRo organic bloom, Cal-mag and Big Bud nutrients
ph way off or root zone issues. calcium starts, maybe even toxicity , i bumbed into one in my recent grow, was thinking its deficiency till all went wrong. too intence light just makes everything worse when they strugle with calcium ...
My first impression is that your temp and humidity is off, so the uptake of water and nutrients is slowed down causing a lockout from buildup of salt, I would get a VPD app like tent buddy and I would adjust my VPD accordingly and I would make sure you keep watering at 6.0 and your leaves might come back but unlikely but the new growth should be much better...But definitely get your VPD checked it's one of the most important things to keep in check where it is responsible for so much...
