LEAVES TWISTING!!

Hey, early this morning I noticed something I've never experienced before... some leaves are twisting! and some more are like in a curved shape

Im thinking of some possible causes...
1.- My plant has grown over 1ft.. its like 13-14 inches by now and has got to the lights, I mean it is around 1inch from the light bulbs. I have 2 30Watt CFL, one 2700 and other 6500 K
2.- roots have got to the bottom of the container
3.- There is not enough light.

Any one please help

Its only this this the one thats twisting, also, when i tried to untwist the texture was like crispy, also I heard some cracking sounds

maybe some burn?
insect?

looks like hotspot burn to me! is there a lot of tinfoil?

Definitely is getting too hot.
