upward taco/v?

hey all i have a question about my plants,they are skunk/haze cross
and i've noticed that the upper leaves kinda look like taco shells/v's
cant post pics but my closet stays hot 88+ daytime grown in ffof using
ff grow big,im having to water quite frequently bout 3 day intervals
the leaves are a tad droopy but they are at least 2" long and very sativa skinny.

I think you have the same problem as me: Heat stress. I was told to keep temps in the 70's
