Why not just use ro and not have akalinity concerns and just continue with cal-mag supplementation? Just a thought....I'd be very interested to see what you find once you get the pH pen. Is it a combo meter by chance?
Here's the little cheapo set up I have in my garden. Takes the PPM from about 220 to about 90.
I think it was maybe $30 or so, including the filter (which probably needs to be changed, thanks guys)
Maybe run the hard water through the cheap filter and then 1/2 and 1/2 with the RO???

Oops...sorry I see why...well ro units are not that high..hell I got one and I sure as hell aint rich!! I just feel it gives you more control over exactly what the plant receives and remove the alkalinity of the water out of the equation on nute calculations... upon which I apparently need to study more

Namaste'
