For your main ferts, go with something like FoxFarms like Loco posted, but Home Depot has some other things you will want to use, like Perlite to lighten your soil, Alaska Fish Fertilizer as a nitrogen supplement, SuperThrive as a stress reducer, Wilt Pruf in case you ever decide to start cloning, and all sorts of pest control stuff.

If you're dead set on getting ferts at Home Depot, there's a Schultz Bloom Plus fertilizer that is not perfect, but I've used it in the past for flowering with acceptable results.
