Do i need Cal mag in my soil when i grow in soil with led light? If yes how much and how often?

It's just a brand of nutrients, and yes you can make teas out of this.What science points to a Ca/Mg deficiency happening due to a light source?? I'd love to read an article explaining how that is possible.
An Mg deficiency .... looking and thinking back on physics/Chemistry/Biology that we should have all had a class or 3 in.
There's only 1 molecule of Mg in the molecular structure of Chlorophyll.
Molecular formula of Chlorophyll is : C55H72O5N4Mg < -- Only 1 Mg atom there on the end.
So back to Physics/Chemistry, "a molecule can not be created or destroyed" (unless nuclear physics). Where would the Mg atom go if there was a deficiency? What would happen to Chlorophyll if there was no Mg atom (creating a deficiency)?
My point is:
Very very difficult to have a lack of Mg since a plant requires very very little. I would also suggest that adding in Mg to a container of soil can cause an Mg toxicity that looks very very similar to a Ca deficiency. Add more Cal/Mag causing more issues..... necrosis.
My suggestion would be to look for a water soluble form of Ca if you're sure you have a Ca deficiency or scratch in a cup or 2 of worm castings with some kelp meal.
Adding in Calcium Carbonate or any of its forms during a grow would be a fools errand at best. Best thing is to have these elements in the soil when plants go in the ground. There are several forms of Ca - short medium and long term release and all should be incorporated prior to planting.
Earth Juice?? Is that some form of Compost Tea??
I had some pretty bad issues in soil which cal-mag fixed. When I took a break from growing I sold one of my Mars LED lights to a friend who used it for hydro tomatoes. He had similar problems with them. I gave him some calmag and it fixed them up almost overnight.

Well said Bobrown14.Soil likely deficient in Ca.. EWC + Kelp meal are your friends. Soil wont be deficient in Mg for plants... I would say almost impossible on Mg deficit.
So Ca shortage is the usual suspect. Cannot add lime or its relatives unless its SOLUBLE ... other wise you will likely change the PH enough to cause lockouts of other nutrients and the end would be near!
Bobrown14 my wife's still mad at me because I borrowed her walk in closet ))That was me thinking again. My wife gets skert when I do that.
He chose to go with Epsom salt for adding his cal/mag just recently I'll let you guys know how they're doing.
