Yellow Fiji Leather closed up, polyps open?

[LesPoissons]

Hi all, my yellow leather has folded in on itself for a week now. Any ideas why? No changes in the last week, polyps are extended but its crunched up. Water chemistry is normal.
(Ph 8.3, 1.026, 0 nitrates or phos, (im planning on moving away from low nutrient tank due to more current research) 0 ammonia, alk/dkh, clacium, magnesium all normal) thoughts? Too much flow? Light?

Might be too much flow. Mine does that every time I mess around with the powerheads.

Ok ill try adjusting that. Thanks. I read they needed a lot but maybe over did it. Its weird that it just got bothered in the last week bc flow hasnt changed but maybe an urchin redirected a power head slightly or something. Thank you
