Some blooms, when spent, form spots on the sepals in the Fall. These spots have dark pink to purple tones. It is normal and nothing to be concerned of. If it happens at another time of the year though, it may be something else.

PS - The blooms in the pictures were not exactly clear. Do you have any closer shots of the blooms?

I thought the first pic was pretty close up, but I'll try to send a closer, later. The comment was helpful though!

Sorry about that. Looks like the plants were recently watered and the blooms are not perky or look wilted or unclear so I thought I would ask if you do not mind attaching another picture to make sure they are really ok? ;o( Thanks you whathousework3!

The first shows a photo of a lacecap with spent flowers (are both photos of same plant?). When the flowers on a lacecap go over, the large sterile florets - those with the pinky-purple spotting - invert and hang down. They may look wilted but that is their normal state. (you can see the remains of the tiny little fertile flowers showing as green 'nubs' in the center of each flower grouping).

Various white flowers will develop this coloration in late season and when exposed to rain or irrigation. Although not wonderfully attractive, it is not anything bad. If you don't like the looks just snip them off right above the next set of leaves.

The spotting on the foliage is not bad and also does not look out of line for this late in the season. Maybe showing a bit of heat stress and the beginning of cercospora. This is also encouraged by a lot of rainfall or overhead watering. When the leaves fall off, clear up thoroughly and dispose of them to avoid reinfection next season.

Yes, Hydrangeas like moisture but watering everyday is for sure much to often.

They look just fine to me. My plants are doing the same and it is normal in the PNW. We don't have to water at this time of the year - we have had rain for the last week or more. Rain is overhead and in the spring they will come back without the spots. I leave almost all the old blossoms on my plants to feed the birds in the winter. To me the beauty of hydrangeas is how they change color for many months and finally signal that they are ready to sleep for the winter.
