So I picked up these 3 frags from different LFS. The green one on the left when I got it was basically all white and over the course of last few months it turn green. The middle purple one roughly stay the same color, however my blue one on the right has slowly start to lose colors and basically all white now. I been testing my water parameters consistently and Mg is always between 1300 to 1350ppm. Ca 420 to 450ppm, dKH 8 to 8.5 phosphate is about .03 to .1 and nitrates is 2 to 5 at most. Salifert test kit for everything. Par is roughly all the same around 220. Apogee sensor with DMM. I have no idea what's going on and hoping someone can help me to see if I could help this guy bounce back.
Forgot to mention, literally everything else in the tank is doing fine except for that one piece.
