Purple and green hammer coral colour

[ClownFish664]

Hi, My purple and green hammer coral seems to be changing colour, the purple is now going down the stem as well as the head, before it had a purple head and green stem but some are now mostly purple. it this normal? Sorry, I'm a little new to reef keeping. Its only a small young head.

Their color is obtained from zooxanthelle produced by light . Assure moderate lighting and water flow as well as nutrients

Thanks, should I increase lighting in that case? Ita a 50l nano tank with an AI prime. I have the light ramp up iverthe day slowly but Max power peak is 21W so it's a little dim. Flow have been decreases due to too much flow making the hammer touch it's skeleton so I reduced it to stop this
