Hi,

was wondering if anyone can help me out not to sure whats going on. Came back from new year trip and plants seem to be screwed up. Theybare under a 600w hps . blueberry cookies, og cookie, and cheese by dinafem. Getting fed flora series with boosters at half strength.

Came back after 3 days seen all this leaf damage . thanks. Flipped 12/12 46 days ago.

Looks like you've got light burn and heat stress.

The yellowing could be caused by light burn, but that can resemble an iron deficiency as well.

Given the cupping on some of the other leaves indicating a heat issue, I'd focus there first.

pro mix peat moss. Everything getting fed the same . Only one plant has severe burning of the leafs. I raised the light up and put a hygro it said 25 degrees celsius. I think it may be heat / light burn. hope it didn't f up my crop to hard.

Did you give a hot load of fert right before leaving? Looks like over fert with high air temp, curling leaf edges, and/or pH problem.
