I have exceedingly hard water in my DWC (275 ppm on a Trucheon straight outa the tap). In the past I've used the typical pH down sold at the local HP store. But to get to a desirable pH I end up with 4-450 ppm before I even add nutes! I know some advocate nutes before pH but all I end up with that route is nute lockout and crust so bad it clogs the system. pH first and then adding nutes seems to limit the precipitate.
Pushing a max 1350 ppm on a grow I'm already giving up a third of the ppm to getting the water right which I can only assume limits nute uptake. Short of installing an RO filter, does anyone have any suggestions on limiting ppm for purposes of nailing the pH? Has anyone tried sulfuric (H2SO4) or muriatic/hydrochloric (HCL) acid as a pH buffer?
Many thanks . . .
