i would not use miracle gro. google a hydroponic shop near your place, even if you have to drive far (i drive an hour).. but they have the best selection of soils, pots, nutes, supplies.. and usually the people that work there will answer your questions. but don't go and ask something like 'what makes my weed taste the best' say something like 'what i'm workin on was just put into flower cycle, and i was wondering what good organic options you have as far as nutrients and vitamins' ya know.. like a headshop, you don't walk in and say 'let me see that big bong' they know what you're talkin about, just keep it simple.. i recommend roots organics products, organic gem, anything organic. i believe thats def the way to go.. hope that helped..
..your pics look nice, but i wouldn't wanna smoke anything grown with miracle gro, personal preference i guess
