That's what I use. I read somewhere that Fulvic is lighter in molecular weight than Humic so is easily absorbed as a foliar. Humic is better at building soil microbe relationships and binding but doesn't really absorb well as a foliar.View attachment 1469787
The good shit! Last round I sprayed with kelp and didn’t really see much growth! This time with the fulvic added they explode! Or sure seems that way!
Either way they will make your plant eat faster which can be good, but also bad if there is a limited supply of nutrients like in organic soil.
