I'd just use a tablespoon of dolomite per gallon soil and forget the calmag,if your water is "hard" it already calcified

BTW, I use PBP, which seems to have less calcium than other brands if hydroponic fertilizer (PBP has 1% Cal whereas GH Flora has 5%). Botanicare's Ca/Mag+ has N plus trace elements that don't seem to be present in PBP. Does anyone think that Botanicare intends for you to use Cal/Mag+ as the equivalent of Gh's Micro? Maybe 5 ml/gal Of Cal/Mag+ and 15ml/gal of PBP(Bloom) would be near to 8 ml/gal FloraMicro 16 ml/gal FloraBloom? All of the above numbers for both brands come from Lucas...don't want to be accused of plagerism. Should I back off any of these numbers due to the 90-100 ppm that are already in my tap water? Thanks ahead of time for any responses!
