Help Jedi Mind Trick purple?

[GlassCityReefer]

I have a Jedi mind trick montipora and it has changed colors, last year I was losing it and this forum helped save it. While the drag has tripled in size at least it has changed to the color in the picture. I will say I am battling Dino because my nitrates were at 0 but now are at 3 ppm. Are my AI prime settings too low I use the AI signature series by Karen Vasquez should I use a different one, like Saxby’s? So is there too much light or not enough or is it because of the nitrate bottoming out? I just started with Kalkwasser in my top off. I am bringing the magnesium up and haven’t done a water change in 2 weeks Becky of the Dino’s
Parameters

Ph 8.0
Magnesium 1170

Thanks for any suggestions!

The purple indicates new growth. Look like it may have gone dormant for a while, and is now perking up nicely.
I would expect things to get back to normal sooner than later.

Oh I didn’t know they could go dormant, that is reassuring, thanks!
