Ok... Not a bad idea, but the fish emulsion's are an additive, and that is your problem. No nutes.

Save your self some time and trouble...If you want to grow simple with proven chemicals and additives then buy...GH 3-part.

If you would rather stay on the organic side, then I would recommend (strongly) botanicare Pure Blend Pro (It comes in soil and hydro formulas)...Buy a gallon for under 30 bucks, and that will last awhile. At least long enough for you to find your niche as far as veggies go...That is what I use, and you cannot beat PBP for veggies...My fruit taste great! 1st time, 2nd time, and on and on!

And you don't change photoperiods in bloom for tomato's, peppers, cucmber's etc...Let me know what you are up to.
peace
