Amino/Humic/Fulvic Acid. +rep for any knowledge on this

I seen the amino and fulvic on ebay and they're both water soluble powders. I have some water soluble humic acid and I was told to mix it in my soil before potting or add a pinch in the water. now the amino and fulvic acid how do I go about using if I was to buy them? +rep to whoever has some knowledge on this.

another thing they both say 2-4 dry ounces per gallon. could I mix these in with my teas?

I have no idea what an amino acid product is, or is supposed to do. It has nothing to do with fulvic/humic acids.

Next step: google fulvic/humic acid and humates, and do some research.

It's not a nutrient, it's not an amendment, it's not something you just "put" just because. Know wtf you're doing with it or don't buy it.

PS: You can fuck up your plants easily with these products and they work best in very very small doses. GO READ.
