GSP needs a boost!

Hi!

Trying my first reef tank after having fish only sw tank. Started with the "hardy" green star polyp mat 3 months ago. It started great, but now seems tired. It opens only about 75% and has stopped spreading. Water parameters are all ok. Mat is in high flow high light area. suggestions?

Thank you!
