About a ml per gallon for Alk.. I initially did dose some Ca but nothing for the last 20 days or so and only a few ml. Your Mg chart is pretty much the same as mine.So just for clarification, since you started the FM Balling Light method you have not added any Ca? Calcium part has Trace 1 and 2 so it is interesting that the tank is happy.
Mg I am not surprised, when I used FM Balling system my tank didn’t need it either.

It was trending up after I added S which contained Mg. Or perhaps the other way around Mg mix that contained S.
Out of curiosity how much Alk are you adding each day?
