What are the temps in your room? What kind of light are you using?

3x3 600 w the temps actually haven't been to bad the really haven't gotten over like 84. I've had to keep my 600w on 50% cuz it's been kinda warm here but my light shuts off at noon. I don't have the capability to use air conditioning with the tent at the moment so I rely on the weather here in socal I was able to turn it up to 100% the last two days cuz it was cold enough to turn it up and it was in reasonable range but when I got home today it was 88 but only for a hour and a half the lights turn on at 6pm

Your venting your tent though right with an exhaust fan. That way your getting fresh air in there. It kinda looks like it. The the crinkled bits brittle?

Yeah they are and the exhaust blows out the top and sucks air in at the bottom left

It might be then given the temps. The tips turned down are generally from over watering.
