It's not the fault of your water source that causes deficiency, it's the fault of the base nutes. There's nothing inherently special about low ppm water. It's just water and most hydro nutes are formulated around low ppm water to begin with.
The bottom line is that cal-mag supplements in general are a waste of money. I've never had to use them even before I did DIY salts. That's the whole point of 3 part formulas like GH flora in the first place! (if you're getting calcium deficiency, you're not using enough flora "micro". Adding a 4th, overlapping, bottle only adds to complexity, not subtracts)
