well i think ppm is for hydro. just the recommended dosage (2 tablespoons in a gallon)
i didn't think i had to start with 1/4 strength since it isn't supposed to hurt plants (it even says). however, it does not have a lot of N, so should i give it a TINY bit of grow big next time since its 6-4-4? or do you guys think N isn't the problem
