Torch Nodules?

[Chemi]

I picked up a torch a few days ago as my first coral specimen. I have it a few days to acclimate and cheer up in my tank. It was doing good when I first brought it home, now it seems slightly deflated and less happy. My question is, what are these pink nodules on the stalk? They are bright pink with white heads. Should I be concerned?
