For some reason nobodies pics wanna load as I'm looking for answers but a couple pics showing just how bad it is might give a definite answer, respiration problems? Heat issues?

I have my space heater set to 75 and it never manages to get it up that high, people were claiming plants under these led's like 80 but I cant get that this time of year. The lights are about 8" from the tallest bud more like 10" from the majority but the lights themselves arent producing much heat and the driver is outside of the tent... I can hold my hand right under the lights for a long time and it doesnt burn

Ah i see. I still think the lights may be too low. I would hang them higher and see if it gets worse or not.

Alright I'll give it a try, do plants tend to recover from this sort of thing pretty quickly?

this is heatstress 100%. room temp is one thing, but temp under the light another. put a vent on them (oscillating) and raise the lights slightly.

No lower than 14" on those hlgs. I use em and done much experimenting. Some plants don't like them that close, even.

It isnt very hot under the light at all, ive held my hand there for long periods of time and it is barely warm. Light stress makes sense though, also I have an exhaust and 2 oscillating fans one on the canopy the other under the canopy

Okay. Also check your strains preferences, some like it hot, some cooler, some can handle more light, some less.

80 is to warm for some plants I would turn off the heater it may be drying things out as well. Good luck!
