milli changing colours?

[fkeeper]

I have a pink Milli that i have had for a couple months that was doing great, nice polyp extension and growth. Then recently it hasnt had as much extension and the colour started to change from a bright pink to a darker purple, and now slowly its beginning to have a green tinge to it. Anyone know why this is happening or what could cause it? as of now my parameters are:

salinity: 1.025
temp: 79
calc: 420
dkh: 8
mag: 1260

how long do you have the pink milli before it starts to change?

po4 doesnt show a noticable reading, no3 is at about 5-10, very minimal. Started changing after about 2 months
