need some nub questions answered please :3

so. i grow indoors, and it's my first grow. They are all potted in some 9 year old compost/dirt stuff my mother calls "black gold". i have 1 re-vegging Pink-freeze and 2 bag seeds. my baby is only about a few weeks old maybe 3" tall. and my middle one is about 2 months along xD i'm currently growing them under 1 48" shoplight and looking to upgrade. my father seems to think we should go for the "aquarium/grow light" flourecents. was wondering if those were any good?
and what kinda nutes should i be looking for?

P.S. just harvested our crop this season and they're drying now :thumbsup:
it's looking good people :rastasmoke:
