NO - too much water. Do not water profusely unless the leaves are still drooping in the morning after a hot day.

Aside from that, hydrangeas drop some low/inner leaves as the season goes on, but if you overwater this will accelerate.

I should add that once lower leaves drop during the season, they aren't replaced by new ones, so you could end up with a plant that only has a few top leaves left in addition to the flowers. I overwatered my Limelight and that happened last year.

...and here I was concerned that they were not receiving enough. Thank you!

If you want to "know", try using a soil moisture meter or test the soil with your finger: add 1 to 1.5g per watering to the soil when the soil feels dry or almost dry. And keep 3-4" of mulch at all times.

Thanks much , i had same problem with a lovely little Fire Light.... I will stop watering so much.

Hydrangeas are one of the first plants to wilt, when they need water, they will tell you. Some wilting in the heat of the day is normal, but they should not look wilted in the morning. Al
