So...the question is:

What is it that slowly kills plants from water quality?

I understand sodium or bad pH killing plants, however I have a harder time understanding how precipitated calcium and magnesium are a problem.

Has anybody tried watering with a divalent cation chelator? Like EGTA or something of that ilk? It might be cheaper than RO water.

Also might help some of the problems that people get with semi-hydro media.
