Is the white part the flesh or is it the pink?
Euphyllia flesh?

I've had these about a month, but the pink part on some seems to moving up but the white has not receded. Any idea why the pink is making a move?

I'm not exactly sure what you mean... if the flesh band as a whole is not receding, the slight color change doesn't mean anything.

Ive just always recalled the flesh being white, these initially had a pink tone flesh (as you can see on the back coral above the 'red line')
the front coral initially had that pink tone where the 'green line' is drawn. But still has white flesh at that same level (green line)
Seems this is a non issue...

The flesh is all that off color stuff on the outside. The skeleton is white. These have lost a lot of flesh on the skeleton and in the picture with the green line the flesh is just below the line of polyps.
For corals you have had a month this is a major issue, not a non issue.
The photo with the split head has lost more than half it's flesh on the outside of the skeleton and you can see a few remnants of flesh connecting and stretched between the two heads.

So the white is skeleton being exposed, not 'white flesh'? Previous post stated 'everything above bare skeleton' is flesh, i took that as below the white.
They have all been opening great during the day. With the exception being the one in the front, he has never really fully inflated.

Correct the white is recently exposed skeleton. It will darken over time with algae, biofilm etc. There is often a small white band as the coral grows upward and the skeleton lengthens the flesh band will move upwards slowly. What you don't want to see is large patches as in your pictures. It indicates rapid loss of the tissue on the outside of the skeleton. New Euphyllia will often have a short period as they adjust to a new tank where the tissue recedes but it shouldn't be pronounced or over a prolonged period where a large portion is lost.
The one in front is the worst off and has almost no flesh outside the skeleton any more. When it is just the polyp attached at the top the ridges can get exposed and make the coral more prone to bacterial infection like BJD. The other two are not too bad with the flesh band still there but they have both lost more than a little so if it continues to progress at the rate it has then there will be major problems.
As you noted the two with less recession open fine and this is typical even though it is struggling and receding. It is using it's stored energy in tissue to continue to open. Eventually the coral will lose though unless the recession is stopped and it can increase tissue mass.
So the question is why is it happening and how to reverse it. It could be one factor or a few factors combined. Full tank picture might help with white lights on so we can see placement, other inhabitants, lights etc. Listing your parameters would be good as well as anything you are dosing or adding. How much and how often you feed too.
If I had to take a very rough guess.. Your rock from what I can see is quite white. So this is a fairly new tank? Parameters could be swinging a bit and bioload is probably small so nutrients are most likely limited. No idea what the par is but Euphyllia can do ok with lower light around 100par so it's not a high bar to achieve. They can also go much higher on par and generally I prefer at least 150. Some keep them lower down with SPS so 200-300 is not unheard of once acclimated. Since they are opening and not tightly closed I doubt the par is too high.
My guess is parameters not really settled on a new tank and insufficient nutrition.

Yes tank is roughly a little over a month old. Alk was at 8 before i added the corals so ive been keeping it pretty stable. Doing roughly 10% WC weekly. Just dosing Alk minimally to try and keep it as stable as i can. Salt is 1.025.
My light is xr15 g6. On 40% intesnsity on the AB+ preset. Corals are sitting 6-7" below water surface. Flow seems okay to me. I have been feeding redsea ab+, benepets reef food, and reef chilli periodically. (Once a week)

Love the rockwork! I think you need to feed the corals more. Your nitrate is fine but your phosphate is essentially 0 and has been for a while. Anything under .03ppm is outside the accuracy of most test kits so 0 could read as .03.
The foods you are putting in are fine but the LPS could probably use something a little chunkier like frozen mysis a couple times a week. Just get ready to add an army of snails and some other algae eaters... bumping up the nutrients is going to make the algae grow. But that is really what you want. If algae can't grow then the corals can't grow because they need to photosynthesize as well.

I currently have 5 nassarius, 5 red leg hermits, and a conch. 1 clown and 1 Pixie hawk. I did recently run out of mysis, so I will get more and start feeding a bit more to see if I can get the po4 up!

@Shirak , good catch! OP, I'm sorry if I led you astray.
