Only one head has looked beat up ever since I got them at the lfs. The rest of the heads are healthy and have actually colored up over the past 2-3 weeks, what can I do?

Have you tried dipping the coral? It might be a bacterial infection and some dips such as Two Little Fishies ReVive or Coral Rx would probably help.
