Your plants are looking good. Residential tap water usually has some calcium in it. You should be able to find a water report online. Just search for “Water Quality Report (Mytown) (Mystate)”
Watching the leaves will tell you if you start to see a deficiency in calcium. Typically random brown spots.
If your tap water is chlorinated you should let it set for a day before using it or bubble it with an aquarium bubbler to get rid of the chlorine.

If your running a soiless or dwc then the calcium and magnesium are a must. But your nutrient line should have everything you need in the main bottles. If your in soil, and using tap water your probably not even gonna need a bottle of cal/mag

Hey @Thumper1 I was just about to comment on the pics you posted on the other thread. It looks like the start of a Calcium deficiency, so this thread makes good sense to me. Make sure your pH is within proper range for your medium (shooting for 5.8ish in hydro, 6.3 - 6.8 or so in soil) before just dosing them though. It could be as simple as a pH adjustment to get them taking up Calcium well. @imSICKkid nailed it, and I’d add to that coco likes to ‘steal’ Calcium from what’s available to your plants, sort of soaking it up before the roots can. And high end LEDs (yours look great 
) are like turbochargers, causing the plants to consume even more cal/mag.

Along with what those 2 lovely potheads above said: Good lights, plus a healthy environment (good vpd) will make your plants eating machines. Sometimes, what looks like a deficiency isn’t, but rather a case of your plant eating too much of one thing, which locks out others.
However, in Coco, true Calcium deficiencies are common.
