GSP new growth turning white?

[mooputingtong]

Hi i recently noticed new growth of GSP is very pale white. Other part of GSP are really bright green but only some of new growth are white. Im just wondering if this is due to low nutrients or supplement issues. i recently did water change and dosing kent marine essential elements just incase its lacking any elements.

new growth in most corals are white. Picture would help along with water parameters for a meaningful advise.
