Hard Water Spots?!

So Iíve had my X5 M50i for about a month. Finally decided to give her a good washing. Had it outside on a clear cool day. Brought it in the garage to dry it. Once it was in the garage and dry I see these water spots on the hood under the fluorescent lights of the garage. So I grab a little spray detailer and they wonít come out! Everything I see online says to use vinegar and water on the hard water spots but Iím petrified. If I take the car outside in the sunlight I canít even see the spots. But back in the garage itís clear as a bell. Iím attaching a pic.
The dealer threw in their Ďceramicí coating on the paint so Iím shocked there are water stains on the car. Could they be under the coating?!

Any help is appreciated. Thanks
