One hammer head closed

[Clowns-corals-cats]

This hammer is normally all spread out and happy but for some reason the bottom head ( the smallest) is closed up. There are other hammers,sps, and Lps corals in my tank and all are fine except that one head. Any ideas?

Too much light or water flow will cause this
Assure also phosphate and nitrate are not elevated And feed mysis 2-3 times per week

It was opened back up this morning. I quit trying to feed my hammers big food like that cause they wouldn't eat it most times and if they did they spit it out usually. Any tips?
