Your calcium is a bit high, you have elevated phosphates, alkalinity and some of your trace elements (iodine, iron, nickel) are a little low. You have slightly elevated zinc and you're showing some tin as a pollutant.
Overall there doesn't seem to be any red flags. Depending on the brand of salt you use the alkalinity may be normal. I'm not sure if you dose alkalinity, calcium and magnesium or supplement with trace elements.
Lighting, flow and water parameters are usually the main suspects. Flow is a visual thing, lighting can be checked with a PAR meter and you can easily adjust (or add) supplements as needed. Without knowing the size of your tank, what salt you use, what % of water changes and how often you perform and what supplements you dose (if any) it would be hard to throw any suggestions out.
You may also want to post some images of the corals in question (and possibly start a new thread) so some of the resident coral experts will have more information to look at.
