Blossoming Questions

I planted three The Original Hydrangeas and one is not flourishing like the other two. It does get more sun 6-7hrs a day starting 1st thing in morning. It is flowering but some of the leaves are turning brown. I don’t see any bugs. Live in eastern Virginia. Used peat moss and Holly Tone when planted.
My hydrangea leaves have brown/black spots on them every year. Other species I have do not do this. Try not to water plants just roots. Can you help me figure out what is wrong and what I can do to fix.

I just bought 2 of “The Original” and noticed some of blooms are turning brown. I’m not sure if I’m adding too much water or not enough water. They are planted in containers with good drainage and the soil is moist. They now only get morning sun. I just moved them so they aren’t getting sun all day long. Suggestions would be appreciated! I live in NY.
