Zoa's being bleached?

[Kevin Blankensh]

Here in the picture are my zoa's that I got from liveaquaria about 3 weeks ago. Lately, I've noticed white spot in the middle of all the ones in direct light however the ones facing away aren't having this whiteness. Was curious if its bleaching since I have it quite low on my tank however I can lower it a few inches. I have 2 arctic S026 led lights on my 90 gal tank that are just laying on the glass.

Can't tell from the picture but white spots on zoanthids usually means zoapox
