Acans both echinata and lords requirements

[Creetin]

I have some lords and echinatas, and they dont look too happy.
I have a maj sps tank with 400 watt 10 ks and lots of flow.
My acans turn drab and do not fully extend. My plate coral seems fine and is growing, but it gets less flow.
The acans will eat at night, and my micromussas do good, But the acans dont like my tank as much.
Do ya think its because the light intensity and spectrum?

it might be spectrum. i have some under 400w 14k and do great.
some are close to the light 6" from the top of the tank.
