If you want to spend money on extra bottles of diluted salts, that's fine by me. It's your decision what diluted bottles you want to dial into. Cal-mag+ completely overlaps with the ingredients already found in flora bloom and micro. If you don't have enough calcium, it means you aren't using enough "micro". Balancing this out by using an overlapping product only serves to complicate things, not simplify. This says more about lucas formula than it does about your tap water.
Calcium nitrate is a very good option on the table, not just for supplementing calcium, but as a primary supply of both calcium and nitrogen. Calcium nitrate is the main ingredient by mass in just about all hydroponic formulas. Calcium nitrate is the key to hydroponics, not just a supplement.
Imo, using cal-mag+ to supplement is actually complicating things more than using straight up calcium nitrate, not making things easier. The only reason it seems easier is because you've already dialed in to the the cal-mag+ bottle. You could just as easily have dialed in to using more of the "micro" bottle, and then using magnesium sulfate if there's a magnesium deficiency. The whole concept of cal-mag+ actually forces the mind away from traditional deficiency charts. The idea that you need to "replace" the calcium you take out of tap is a flawed idea to begin with. GH micro is the bottle that contains calcium. If you lack calcium, you need more GH micro. There's a reason GH made the flora series a 3 part mix. It allows you to fine tune your nutrients.
