I've heard good things about fox farm... There are people that swear by those nutrients... I have used their soil and a box of steamed bone meal which was all top quality. It was kinda expensive though. I Currently use GH Flora Nova and GH BioBizz and can recommend them both. The GH FN is half organic half chemical... so it feeds the soil and has readily available nutrients already. Its hard to work with though because its a really thick sludge kinda consistency. The GH BB is great also... It seems to work just as well as the Flora Nova and its all organic. FloraNova and Biobizz are molasses based. I also add 5ml/g of organic unsulphured molasses, I use liquid karma, superthrive and ocassionally hygrozyme.
