Hi all, i'm starting to notice some chlorosis in a few plants, my fertilizer isn't super complete with the micronutrients and i've been laying off the one with all of them cuz they have a lot of the macros and i don't want super growth right now. i'm pretty sure it's a micronutrient problem, so what i'm looking for is sources of micronutrients that don't contain macronutrients, someone mentioned epsom salts before but my fertilizer actually does have magnesium (also calcium and molybdenum). i'm particularly interested in manganese...
