Definitely not normal. It is a digitata though. How long have you had it? Where is it located in the tank? Do you know the water params and lighting from the tank it came from?
I also agree on bringing the Alk down slowly. I keep mine at 8.5 and feel my SPS do best at the level.
This is what the polyps should look like, minus the blue lol...
