I just ordered Jacks 20-20-20 liquid fert online for $16.00 for 4lbs. The microblast is around $10.00 to $15.00 online. As far as the light goes I didn't see how many plants you had total, but I would say one of those lights for each big one should work out. They will probably say you need a exhaust fan, but I'm running my shit outta a closet with a fan also so don't listen to me on that one.
