Lemon Lime Toadstool - All 3 not extending polyps

[Spicy Reef]

I've had these over a year now and 4 days ago each one stopped extending their polyps....

two on the first day and on the 3rd day the 3rd one stopped as well.

I've had these fairly stable for 3 months now

ph - 8.2 red sea milwaukee
alk - 9.4 hanna salifert
calcium - 400 salifert
mag - 1410 salifert
phos - 0.0 api and hanna both agree
salt - 1.026
N03 - 0 red sea
amonia nitrite 0 - red sea

I feed twice a day flakes, frozen and alternate in seaweed for the "tang" gang

I added some activated carbon today and plan on doing 20% water change tomorrow.
All other corals look normal with full polyp extension.

This is the reef and what they looked like 5 days ago...

Any thoughts?

I've read where the leathers go through a shedding process 2 - 4 weeks.
Could this happen to all three at the same time?

Assuming that your leathers came from the same mother colony, it’s not unheard of for leathers to go into shedding phases at the same time.

One popped off the large one on the left the other I fragged from it.
I hope it's something simple like that. I can't think of anything else to look at. doing water change right now

What causes rot?
Ok, something more is happening to one of the LemonLime's
The toad stool from the very first picture above is starting to "rot"?
Should I "frag"/cut it off?

@Spicy Reef I have no advice (my apologies) but I did want to comment that those are some nice looking leathers.

Any photos of what they look like with their polyps extended?

Any updates? Did it end up continue spreading?

I unfortunately didn’t see the notification for this thread so couldn’t help but I would personally check every parameter.

The big one and small one have started to make a "comeback", I never saw any slime or film so I don't know if that's what happened?

The medium one came back two days ago but polyps decided not to come out today...

all polyps are about 1/3rd the length they were a couple weeks ago... here's a shot of the big one a few minutes ago...

I'll post again if things "go south"
I have to think this was the shedding people talk about, but I just couldn't see it, maybe my glass is too dirty

Leathers, especially toadstools are weird as heck sometimes. I just leave them alone and 9/10 times they come back just fine. I have had one for 6 months that hasn't grown an inch but has very small polyp extension so it's not dead.

Based on locations, they may not be getting sufficient flow. When this happens they haze over on their caps/heads and curl.
Take a turkey baster and give their heads gentle blasts and then direct flow towards them - Not at them and you'll see them perk up
