Fox Farm, 1/4 strength, after plants are 3 weeks old

were can i get fox farm?

local hydro store, or ebay. You dont have to use that, you can just buy a soilless mix at local walmart or lowes, or home depot, also buy some perlite, vermiculite... peat moss, building sand, worm castings. Mix that up and Waaaalaaaa. Got yourself a soil mix, then Pick up some Nutes, and go to town.
