Need a little help!!

Ok i got 3 plants about 3 feet tall! i got them under 4 100w cfl's about 2 in from top bud! got them on 12/12! Now i need to know what i should feed them now that they are indoors!

I take it you're growing in soil? FoxFarm does a decent range of bloom nutes to be used when you water your plants.

Also, I would spread your bulbs around the plants, rather than have all four bulbs at the top because your plants are super tall.

Pics? Is this your first grow?
