ppm of tap water - whats tolerable?

[gainesvillegreen]

if my tap water is in the 400s, could i just dilute it with distilled instead of using just distilled and adding cal-mag? my goal is to not have to buy tons of distilled water and not to have to add cal-mag

You absolutely can, that keeps a good level of the nutrients you're missing in distilled alone.
