Leaves are curling UP. HELP!

This is not my first grow. I have been very successful in the past but I am having a problem with my new baby.

Her leaves are curling up. Everything else about her looks to be perfect.

Under a 400 mh lamp.
In FoxFarm soil.
Foxfarm Big grow nutes were added at 3 tsp per gallon
temps are 74-86
humidity is 25-35
plenty of ventalation with osc. fan.

HELP ME PLEASE!

well I have a nother leaf that's turning yellow and starting to get a bit brown, I fed my plants a little less then 1/4 strength on friday, I am using 42wCFL and 13wCFL and my room temp is sitting around 25C my 42w is about 3 to 4 inches from the top but all the younger leafs closer to the light are fine

they are probably suffering from heat stress
