if all the cfl are above the plant the light from them won't penetrate down to your lower leaves and they will turn yellow and die.......try getting more light to the sides of your plant too.

LST you plant next time.... lst is great for cfl's.

Looks like it could be a Mg-deficiency. The older leaves will be the first to develope interveinal chlorosis. Starting at the leaf tip and progressing inward turning to all yellow or brown

This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water.
