Coral polyp extension and heads open most at night?

Most my corals look the best at night... Polyps extending out and reaching far... During the day they are retracted... What does that behavior usually mean ?

So for example,
- the Duncans are closed during day but out at might
- Zoas completely closed or peeking in daylight but open at night
- birdsnest retracted during day, but open at night
 
I'm guessing too much light?? I see you have LED's try tuning them down some for the first 2 hrs in the morning and see if they respond.
