My leather coral waa doing great. Good polyp extension then it shed. Now it hasn't fully opened again and has almost like clogged pores? (Pic attached) is this normal or should I be concerned?

Thanks in advance for any help

They like strong light and strong flow. I have my leathers high up on the rock work. Maybe move it up out o the sand and see if that helps.
