Sounds like you need more CFLs if you are experiencing stretch + little foliage (they should be 1-3 inches from the plant's foliage), maybe use some pruning techniques to help with the stretch. (LST'ing, topping, FIM'ing)

It sounds like transplant stress. (heat stress usually results in curled leaves). This could take a day to a week to overcome and continue normal vegetative growth.

Keep a close eye on your temps though - heat stress is no fun.

Don't try any pruning techniques until you have recovered from the transplant stress.
