Hi, Mine is looking really nice except for some of the leaves are curling up on the tips. At first I thought it was a nutrient defficiency so I changed my nutes to FoxFarm GrowBig. Nope, nothins changed, anyone know? Thanks Oh, I also checked nut burn and I have been feeding it normal water and no change.

Well I don't know what to tell you. Curl like that is from heat stress. Some will do that even at 80 degrees. It could be humidity but, realy I have never seen solid evidence that humidity causes problems like that.

I agree smkn... that heat stress for sure....
So what are your temps in the room???
Ok now check it right at the plants whats that read? my guess is 85-90...
Get a fan across them ... my 2 cents.

Yo one of my plants is doing the exact same thing and I know its not heat stress because my temp usually averages out around 77 degrees....the really weird thing though is that this is only happening to 1 of 4 of my plants, my other three are happy as can be....please solve this mystery I would appreciate having 4 plants instead of three

Maybe a combination, heat stress, low humidity and low soil moisture,....or any of the 2 combined

Nope im actually pretty good at growing weed so all of my environmental conditions are spot on... temp stays between 77 and 83 degrees, my humidity is 45 percent and my pH is 6.0 in organic fox farm soil....this "leaf clawing" is only occuring in 1 of my 4 which is the real mystery....some one please tell me what causes this or atleast tell me im over reacting and my plant is fine
