Hard water vs. Salt softened water?

I have 2 choices for water. 1 is hard at 25 grains heavy calcium. The other is soft containing 750mg/gal of sodium and run threw a dechlorinator. Can I get away wait watering with the soft water then dunk flush every 2 weeks with the hard water? I'm looking for a cheap solution. I have been able to finish plants with both waters.

The sodium would be pretty high, you might be able to run it through a filter like a Brita, to bring the Na down. What is “heavy calcium”? What are the ppm’s or mg/gallon of Ca? I have well water that is extremely hard 400-1400 ppm’ with most being Ca, Mg, and Mn, with some sulphur, Fe , and Bo. I don’t treat it at all.
