try a 15 30 15 fert. as far as lighting goes for fl's, i just found out today that the kitchen and bath fl's are the perfect spectrum for flower(2700k). ne way double check me on the nutes, i just started my first inside grow(mother nature always took care of lighting for me so i may be off, just thought i'd pass on some of what i've learned from others wiser than myself.

good luck!!:thumbsup: :dance:
