Anyone using amino acids in coco dtw?

Ordered some ferti nitro plus which is 80% amino acids and 13.62% nitrogen. Label says the dose is 1-3 grams per gallon, which seems like a lot, but I don't want to add too much N. Anyone here experienced with aminos know the common dose in drain to waste hydro? This is the percentage of the aminos

RAW npk has an amino acid with 7-0-0 and it only has glutamic acid and glycine so I'm guessing it's the same thing as ferti nitro but with the other aminos filtered out. Their recommended dose for hydro is 0.6g per gallon. I'm using 0.25g per gallon of the ferti nitro & adjusted my nutrient formula to account for the extra nitrogen. Plants seem to like it I'll eventually try to up the dose. I'll prob try 0.6g for my veg plants & will update how that goes.
