did years of testing nutrients in hydro, best yield to cost ratio hands down go with general hydroponics maxi grow, maxi bloom.. great stand alone nutrients for beginers to experts, great yields, just do a good 3-5 day flush at finish...
believe it or not, even tho its a cheap nutrient it stood up to serious testing against the higher priced nutrients.. in my tests advanced came in 4th place under 1st gh nova, 2nd foiliar pro, and 3rd plant life 3 part,,? but in my water those wer the real results after years of side by side tests in 4x4 f&d tables...
