He is right, dont forget the dolomite! For bacteria molasses would be good right Coho? Coho is also right FF is a little more expensive and honestly not much difference from local nurseries dirt.I add perlite 30%, dolomite and epsom salts..also beneficial bacteria. Bone meal, blood meal in limited quality--. I've used MG organic with fine results. I use GO nutes. FF and Happy Frog are nice but $$$$$.
