One thing for certain..temps are high...leaves are showing alot of curling! The only time i had this happen was when i had to move a plant in my closet and it was warmer in my room with lights out than in her regular space..the plant had yellowing 6 hours later when i took her out..she was 100% perfect the night before when going in..harvest went well though. The yellowing was more uniform though..odd leaves here and there, but it was together..not all patchy like this.

Interesting. I've had heat stress but never to that extreme. I just figured they would wilt up. How hot are we talking?

if those burns appeared over night it is probably either nutrient burn or a root rot issue

it does look very similar to copper deficiency, but your PH would have to be way off for that to happen.

Thanks for the vast knowledge guys.. I've narrowed it down to pH, heat or oxygen deficiency.. Lol definitely no cat or racoon came and took a piss. Room is sealed off
