My recipe (my book, p. 87) is for providing hardwater nutrients (Ca, K, Mg, etc) to plants. I purposely use CaCl2, because it does not raise the pH. If you use CaCO3 (as in dolomite lime, oyster shells, sea shells, etc), you will increase the pH, which is something that I would try to avoid.
Won't baking soda, as part of increasing carbonate hardness, increase pH? Is there any way to avoid that, if you want to keep the water soft? I thought kH and pH are pretty inexorably linked, though I must admit to not being too familiar with the chemistry behind it
