Hello local reefers. I need help, as I am banging my head, and not sure what to do.

I was given a Jedi Mind trick montipora capricornis (see attach) that is no longer green as it should be. Its currently all purple in color. But appears to still be growing, although at a very slow rate. I am lost as to why it lost it's color, as I have tried different lighting color schemes, different levels within my aquarium, and flow. I also have some different montipora capricornis which has now dullied in color (green originally, now grayish / bright red originally, now pale red), and then I have another montipora capricornis which developed a rather large white spots on it. Obviously things aren't right in my tank, but I need assistance as to which path i need to take.

List below is info which might help.

Salinity - 1.026ppm
Ph - 8.20 (day) - 8.05 (evening)
Magnesium - 1350
Calcium - 420
Alkalinity - 9.5dkh
Lighting cycle 10am - 10pm
Lighting - LED provided by radion ECOtech (model rx15 pro) 4 of them. intensity is at 45%
Tank - 150 gallon (tall)
Phosphate - 0.30 (tested by hanna checker)
Nitrate - 10-15ppm
Nitrite - 0
Ammonia - 0


Thanks
 
I'm pretty sure jedi mind trick is a montipora undata, not a capricornis. That said I've never seen it turn purple except at the growth edge so I'm not sure what's up. Your nitrates are a good bit higher than mine, but my tank is an oddity like that and I'm not sure yours are unreasonably high.
 
Phosphates are too high... Should be 0.03 instead of 0.30 Are you using gfo or similar?
 
Not using GFO. What is weird is that my friends tank that has been up for years is showing 0.6ppm of phosphates. And since he have me the Jedi mind trick, and his is looking great, I'm a bit confused
