KEEP IT GREEN

Hard to tell but maybe rust. Pics of the plant would be better. Maybe some more info on the room and grow style. But forsurly keep it green

Im not positive but i see multiple problems, One being heat stress and some deficiency

What def. do you see hilltop? Werry420 you might want to pull your plants out of there. Just kidding. I'm not sure heat stress? Could be the leaves are curling up? Those spots are rust spots I think.
