Everytime I add calcium, the PH goes up a little.. Is it possible to have it not go up...
I have added gypsum (calcium sulfate).

I just added limestone (calcium carbonate, i think).. I know this will raise PH too.

I'm actually surpised on how much plants need calcium.

My understanding is that calcium will only raise Gh and therefore shouldn't affect Ph. The carbonate in the calcium carbonate will affect Kh and Ph. Maybe something else is going on?
