Dyna Gro. LOL give a whirl man, Check out Homebrewers Journals. I have used it for about 6 months now in perpetual cycles. With Great success. I recommend Foliage pro, Proteck, and Mag pro for Veg, And the Grow/bloom 50/50, proteck and mag pro for bloom.
now if you want to get into additives look into green planets massive.
