i would say YES and you can make Cal -Mag from CALCIUM NITRATE and MAGNESIUM SULPHATE
roughly 25% Calcium and 15% Nitrogen and MAGNESIUM SULPHATE (Epsom salts or magnesium and sulfur) 10% Magnesium and 13% Sulfur.

Calcium and magnesium are both needed in fairly high amounts from plant. Most soil companies have added lime to bring down the acid of the peat and adding a product meant for hydro can have a negative impact. Not 100% sure what you are trying to do I guess but if you are referring to adding a product like botanicare calmag, there are better ways in soil to get calcium like gypsum (calcium sulfate).

I've been told that city water requires cal/mag where well water doesn't. I know not other than what the " grow store guy" told me too. Any comment on that?

Auto grower here. My organic granular fertilizer must contain sufficient amounts, in that I've never experienced a deficiency.

There should be enough calcium and mag in potting soil and tap or well water.

If using ro or distilled water it is a good idea to add cal mag as it bufferes the solution. Which helps keep soil ph stable.

well water is usually “hard” which means there’s calcium and magnesium in it allready in a high dose. City water is usually treated with minerals as well including cal and mag. R.O and distilled water def need cal-mag. You can get away without adding cal-mag to city water depending on the ppm that’s been added.
