Are my corals doing alright?

[donutmanstan]

I just started a 15-gallon Innovative Marine almost 2 months ago and added coral about 1 month and a week in.
Some of the corals are acting strange, and I was hoping someone could tell me if they're being given too much light/flow.
I bought a large toadstool, a small toadstool, a hairy mushroom, 2 gorgonians, a devils finger leather, a small kenya, and a large kenya.
The large toadstool extends its polyps very well, while the devils finger tends to only have one head with extended polyps at a time.
Gorgonians receive lots of flow and fully extend their polyps.

PARAMETERS:
1.026 salinity
0 ammonia
0 nitrite
5ppm nitrate (trying to raise this)
phosphate not showing
PH 8.2
temperature 77F

I have 2 powerhead running low pulse, and the toadstool loves it. There is a good amount of water movement.
I have an AI prime running from 8am-5pm at 50% white, 55% royal, and 70% blue.

Pictures in natural light:


I know the kenya tree is turning white and I would assume its due to too much light?
The shriveled up one i think is a large kenya, is it doing alright? I'm thinking i might be giving it too much flow.

Thank you for any insight!

The lack of any algae or anything on the rocks is concerning especially with that much white light. You need to get phosphates in the tank. And I would lower the the lights and add in some UV to the spectrum.

If you’re actually reading 0 phosphates that’s likely the issue every tanks needs at least a bit of phosphate. Maybe that’s why they are closed
