Frogspawn help?!?!

[O3reefer]

My tank has been up for over 6 months now and everything is growing and looking great. My lights are 250w MH 14,000k with 4 actinic. My frogspawn originally had 2 heads, the it had lots of babies, and then the 2 heads split and split again. recently the purple tissue at the base of the heads have been either turning white or the tissue is receding. The weird thing is that they still fully extend during day and the colors look great. I do not know what is going on with the tissue at the base of the heads around the stalk is doing. All other corals are doing fine

Is the tissue just receding to the individual heads?

Should I be worried?
here are some photos at nighttime so you can see what i am referring to

It looks like tissue lost. Frogspawns don't lose tissue when it splits, it should have tissue surrounding the entire base of each head. Yours looks like its losing tissue at certain spots. Now, has anything changed lately? Temp swings, alk swings or low Ca ect...

First thing I would check is your alk, cal, mag water parameters. Also nitrates and phosphates. IME Frogspawn doesn't require strong lighting and it likes low flow, so it does best near the bottom.

If the polyps are extending then I don't think you have a problem.

It has to be water parameters causing tissue loss
