Which nutrient additivies?

[shaunr97]

I am using flora series trio (micro, gro and bloom) along with VitaLink CalMag. I am going to be using FloraKleen.

I was thinking which one should I add?
Humic Acid (Black Diamond, Diamond Nector, ect)
or should I just stay simple and add Molasses?

If non of them what would be 1 more additive you would add if u can only chose 1?
