Hammers showing signs of stress? Need help

[nomad6]

Got a couple of hammers showing signs of something. No changes that can be noted alk- 8.5-9 ca- 420s mg 1350+ no3- 4-8 po4 0.04-0.08 Started w one and spread and is confined to a certain area, from the pictures you can see what I’m talking about. These spots appeared over a couple of days. Was thinking probably low nutrients (uptake is high) w a combination of light issue. Wanted some expert opinions before I took corrective action. Tank is mixed reef, jam packed w euphyllia. I dose on the daily for nutrients and keep up w major and trace. You can see they’re healthy but not too sure of these spots. My Coral guy, RJ, said nothing to worry about but a second opinion wouldn’t be a bad idea, TIA!!

Never seen this spotting before on euphyllia.

What kind of "corrective action"re you planning? Keep us updated, and lets see if anyone else has seen this one?

I’m thinking it might be bacterial, so a series of iodine dips if situation gets worse
