to me it looks like your corals are reaching up for more light, they want more light IMO
 
The few pallys that are opened are reaching. That candy cane is reaching up. how many watts is your light and how big is your tank?
 
All of your parameters are on the high end of acceptable. This is definitely leading to some stress in the corals. I would try to get things back to closer to natural seawater levels. I would also reassess your lights.
