Acropora base white???

[Jake_the_reefer]

so i got this frag of red planet quite some months ago and recently I have noticed that the encrusting base and the base of the acro is pretty white and I'm not sure why. Is it bleaching? Could something be wrong in my tank?
Salinity 35
Alk 10dkh
Calcium ~450
Mg ~1300
Nitrates 2
Phos .05
Par ~325

All other acros look great and are doing very well. One thing to note this acro has lost color but is growing super fast. Ill include a picture of when I first got it, after it colored up and now

The first and final pic are exactly 2 months apart (guess I didn't have it as long as a thought)

Looks good to me. I do not keep red planet anymore, but mine were always red and white.

Red planet can really change based on location. Try moving it down a bit and your likely to get more green. I see that may bit be possible with your scale though.

Okay so its common for red planet to take this coloration? Good haha id hate for it to be dying, its grown so much in 2 months
