After looking at your two photos and particularly the top photo which shows the hydrangae plus other plants, I am seeing twisted and deformed leaves on those plants as well. I am wondering if your plants have suffered from a herbicide drifting over to them. The high temperatures and humidities we have been experiencing in Illinois are very conducive to volatilizing herbicides and we are seeing more than normal, this year.
In the spring and early summer, it is common for people or lawn care groups to apply herbicides that control broadleaf lawn weeds and many of these products can move off target in high temperatures and windy conditions. Another herbicide that is commonly used, RoundUp, can cause leave stunting and yellowing in small doses to plants. From your pictures, it does not look like aster yellows are the problem.
As far as your hydrangae, pamper them this summer. Water when the soil is dry, do not overwater them. Overwatering leads to root rot and plant death. After Labor Day, fertilize them to support winter survival.

Thanks Doug; I wasn’t at home when our lawn treatment applied, so guessing that may be the case. Will certainly keep pampering them; glad I didn’t just pull them out as we love our hydrangeas!
