I’ve been following the pro’s and con’s of lean dosing thread and I have seen this issue come up a few times but not really explained. What exactly about “hard water” causes precipitation and uptake issues and is it more Kh or Gh related? I know many people like myself are not using RO so some of these regimes are not so cookie cutter with results. I know “watching the plants” is the most obvious answer, but chasing deficiencies is a quick rabbit hole to disaster for many. For those of you more scientifically inclined, please explain for the rest of us peasants please! Many thanks
