Hollands Secret from extremegrowing.com (future harvest development) is amazing food. Cleanest ive seen run threw aeroponics.
Its sold at betterthannature.com and at there local outlets in the peg.
I use Holland Secret 3 part
Nutrients from Better Than Nature
And Phosophoload
Phosphoload - 1 liter - Misc. Nutrients

I do add some Groteks monsterbloom or bud boom from advance nutriants
at times and found it to be as good as Holland secrets additives .
Anything else just lags
You can get away with just using 2 parts to a 3 part food, ie. Lucas Forumla which works well, and depending on what type of hydroponic set up you may need to add some Magnisium to the resevoir during the cycle, but that you learn along the way!imp:
