My mushrooms have started shriveling up and are not opening in full bloom anymore......any ideas?

Water quality is great.

I added new lights 260W PCs but there were doing great after that, bigger than every.

I started using Calcium suplements, you think maybe too much calc in the water????? I got a Calc test kit today to test.....

I also moved them to a more shaded are of my tank but still the same...

All my other corals are doing great......
