Has anyone used either of these as fertilizers during flowering? I'm leaning towards TKPP because of the potassium but at 50% concentration TKPP has pH of >11, but that is about the solubility limit.
I can buffer this down with CaCO3 but really looking for someone who knows what concentration and how much. I only have a few plants and don't want to screw them up!! I might experiment on one?? Any help is much appreciated.
TSPP is tertrasodium pyrophosphate and TKPP is tertapotassium pyrophosphate. The have many uses but haven't heard of anyone using them as ferts....might be a reason why, but both are cheap and have lots of the required nutes.
