pick up a bottle of superthrive for early veg, 1 drop in a gallon will speed up your growth early on.. also you want a heavy nitrogen fert for vegging, i suggest peruvian seabird guano, it's available at most online shops. make sure the npk is around 10-2-0, you'll be making a tea from this... also purchase a bottle of schultz cactus plant food with an npk of around 2-7-7 for flowering.. this will cover everything peace and good luck
