I've been doing dwc hydro and soil for a while now,and the best nute solutions for Veg. VS Bud nutes in DWC is as follows, Best having RO (reverse osmosis) which allows very low water ppm, Fox Farm veg. which does not make your roots all slimy and black,it is a chemical, fast nitrogen absorbing solution, and the color of it is aqua not black::: Now,your going to need a catalyst right? right, people say it's bad to mix organic and chemical nutrients because one might block out the other? wrong, your going to need some kind of catalyst so it's either,"KARMA", OR, "FLORALICIOUS". Karma is an organic catalyst vs floralicious which is chemical. A catalyst helps facilitate all your essential nutrient to be taken up by the plant at approx. double the rate. Thats what you need for your veg., now for your Flowering I've found it best to use Floranova, which is a chemical fertalizer, and to use karma in conjunction with that at smaller lvls than veg. I've gotten the best results by using this formula, I hope it'll work for you. STay Up OregOn. Dont leagalize marijuana. Smoke joints.
