Planted a pair of Hydrangeas about 4 months ago, doing pretty well, it wasnt till about a month ago that I noticed some weird spotting on the leaves and they keep coming back after clipping these leaves.

can anyone identify whats on the leaves, whats causing it, and what I can do to eliminate the problem.

if it helps, Im located in NC, where the temp has been pretty regular these last 5-7 weeks (65-75 degrees)
