Excuse me Doctor My leaves are curling up!

Hey all so my leaves on my "big girl" (at least I hope) are starting to curl a bit wasn't sure why this would be was thinking maybe heat?? I'm sure it's not underwatering I have dropped a few pics on here if you have any ideas please let me know

Same thing happened to me when I used cfls...
The problem was my cfl's were too close to the plant.Try backing your lights away a few inches, see if that helps.

It is also possible there are other factors in play that I am unaware of. Lets try one thing at a time. If it doesnt work, we will try something else.
What are the temps? Do you have a fan blowing on them?

temp is 75 to 80 and yes I have a fan and it is vented both intake and exhaust


Here is a pic of the lights maybe they are to close




I was thinking that they might be to close cause I have burned a few leaves from them touching but didn't want to have them to far as to stretch the plant..


Thanks for any input you have

Your room is 75-80. Under the plants is obviously too hot. Back it off a bit. Lights radiate a lot of heat.

ditto

take two pills of advice and call me in the morning...

haha j/k

See the slight curl in this pic. This is heat burn on one of my girls. What's done is done. New growth will be fine if you back it up a bit.

mmmkay so bulbs further from plants and some more air circulation. Should be pretty easy......Thank you!

so if the heat is backed off will those leaves return to "normal"?

No, whats done is done. New growth will be normal though.

Alright well I went to the local wally world today and picked up a couple fans and hooked them up to my unit one inside to blow out the hot air throught the vent in the top, one on the outside to blow through the intake vent and one inside to blow on the plants I lowered the temp of the unit about 10 degrees F as the room as air conditioned but the bulbs I'm sure were putting out quite a bit of heat. So you said whats done is done understandable but will the curlled leaves hurt the "performance" of the plant?

Also off subject but about when can you tell the sex of the plant? Not til I switch to 12/12 right???





This pic was taken before I cut the vent holes but it will give you a idea what I had going on.




Thanks for your help Northeastern kiss-ass

Glad I could help. And no it won't hurt. As long as the problem is corrected your fine. And Yes you could tell sex after 12/12 for about a week or 2. The strain i'm growing will show preflowers after a few months inside, though it isn't flowering. Just a sign of sexual maturity.
