Alveopora and Lobo are Unhappy, thoughts?

[shew]

Hey all, Slowly over the last 2 weeks my LPS have been going south. My Lobo for the last 2 weeks has been looking very deflated, has started to bleach, and even has some algae growing on it. I tried feeding him every so often, but usually the food just sat in his mouth and he wouldn't eat. 2 days ago my alveopora stopped coming out of its skeleton as well. Both pictured below. I have a green kenya leather that doesn't seem to go as tall as he used to as well.

I have Euphylia in my tank, 2 hammers and an aussie torch. They have been out and happy this whole time. There's also GSP, a weeping willow, another toadstool, and pulsing xenia in my tank. Those 4 are all happy. I also have an elegance in my tank that has been dying of elegance disease for about a month, but im working on it and am mostly concerned with the LPS right now slowly getting worse.

Any Ideas?

Params:
Salinity - 1.024
Alk: 8 dkh
Calc: 370
Mag: 1380
Nitrate: 1-2.5 (probably around 1.5/1.7)

Do you test for phosphate? If so, what is that value?

The nitrate may also be a little low, some LPS corals like a little dirtier water.

i don't test phosphate because I unfortunately don't have a test kit for it, but im ordering one right now

I'll try to increase fish feeding to bring up nitrates

Got both a good news and bad news update

Good news is that the Lobo has started to inflate a bit for the first time in 2 weeks! I also got my phosphate test kit (salifert), and my phosphate was under .03

Bad news, the alveopora seems to be getting worse here's a pic:

Still no idea why it refuses to come out, any ideas?

I doubt this is the cause but just reading, seems your calc is on the low side
