There's just soooo many things on the market, some I have tried, but most I haven't.
I do like CX Nutrients Head Masta, Green Planet Dense and Monster Bloom, AN Big Bud Dry, CES Uncle John's Blend, H&G MultiZen, MOAB, Botanicare Hydroplex, Botanicare CNS17 Ripe, HCO Magnum, and probably 3 or 4 I cannot remember - I know there's a bloom kelp supplement and a silica one that I liked a lot but they are off brand.
There's a time and a place for all things. You're not going to find magic in a bottle. It's elements and hormones mostly, and genetics trump all. Too many growers drop $100 on bloom additives but cheap out on their ventilation fans. Once all the other factors are dialed in, that's really when to start looking at supplements.
