Green Star Polyps didn't open today

[TitanVA]

I have had a softball size rock covered in GSP for a little over a week now. They have been thriving since I got them home with no issues. My wife just called me and told me they did not open today. What would casue this to happen and are they ok? All that is in the tank is 2 perculas and some zoas and they are all fine. I have 2 tunze nanostreams and a maxijet 1200 in a 54 corner, so the flow seems ok. Any ideas?

Thanks
