GH 3-Part will work fine on its own till you get your legs under you after a few grows you might want to try an additive or 2 but not super neccesary. From the info I got from my hydro shop the Floranova is more geared toward soil and the original 3-part for Hydro, if in fact that is the concrete truth I dont know but is what I was told.
