im no expert but i think this might be due to the temps. i had this problem when my temps were high.

heat or wind stress from the looks of things, you got a fan on them? this will pass as they get bigger as most plants do this in a farm.

i wouldnt worry mate, its not any real problem i have a wilma system and mine do this sometimes i think its just shock from going into the system and being put under hid lights im geussing your using hps right? In time it grows out

what you got a fan on them? like blowing directly on the plants?

[Bobby Digital]

like i said before it is common and not really too much to worry about it should pass as the plant grows.
