Ca will have no effect on the shrooms.
Keeping a chemistry balance will.
Shrooms can and do better under very bright light-just do it slow. Mine are under 400w MH less that 10 in under the surface, some as much as 2 in under.
I do not use carbon or other such products.
I feed heavy.
I skim about half of the week.
I have decent to low flow.
A constant temp.
Shrooms will adapt to most aquariums but IMHO they will thrive under the above statements. good luck

CA has no effect on shrooms and the addition of CA does not lower the alk. Alk and Ca drop due to calcium carbonate/skeletal building organisms, mushrooms are not one of these.
Lots of misinformation in your post, but thats just a start.

They are getting small because when your lights go off, your pH begins to drop.
When your lights are on, the pH returns to its normal place. When the lights are off, algae begins to release CO2, and your pH goes for a rollercoaster ride. That's why the LFS asks you to bring water in to be tested after the lights have been on for a while.
And if you skim only half the week, your skimmer isn't working at peak capacity.
