Some Espoma Flower-tone 3-4-5 should give u pla=enty of the macro's for vegging, along with some N-rich guano, and worm castings... Then u can continue the Flower-tone, and begin dialing down the N, and giving it mor P-rich shit like rock phosphate, bone meal, P-rich guano, etc... Itz always good to have a well-balanced mix of perlite, vermiculite, greensand, dol. lime, a dash of epsom salt, peat moss, cotton burr, coco coir, etc, all in a good-organic soil(not MG), and even have a layer of pea gravel on the bottom of your containers, to aid in drainage, as well...
