New zoanthids polyps not as colorful

[chemicals]

I’ve noticed that new polyps from different zoanthids are a lot less colorful then their “mother” polyps. What could the cause be?

salinity: 1.026
Temp: 26.5 C ( 78.8 F)
Nitrate: ~7
Phosphate: 0.04
Alk: 7
Calcium: 420
Magnesium: 1280
Par: between 75-150

I have color variations within the same colony, so it's fairly common.

Sometimes they will have different Variations and also it could take some time for them to grow into the actual color of the mother colony.
