Ideally, You want Ca levels to be about equal with N and Mg about 1/4-1/3 Ca. Are you suggesting I increase calcium and magnesium to the same ppm as nitrogen or raising Ca and Mg to 1/4-1/3 of N?

I only have a dozen or so plants-granted they cannot be picked up at the supermarket-I really can't justify buying more and more things. I need to work with what I have as much as possible since I have more supplies than plants.
Just looked this up: 3-24 ppm Ca in water supply
Epsom salt will get me the Mg. How do I get Fe (rusty nail?) and Ca (egg shell?) and how much?
