Cercospora or Anthracnose?
We have some hydrangeas that were planted in a couple of months ago. Our complex's manager put them in and has been watering them. The other day I noticed blackening of the leaves with some spots that look like something fungal? Not being an experienced gardener, I need some help identifying the problem.
From what I've found, this is probably cercospora or anthracnose, but I can't tell which. Here's a detail of the damage, any idea which this is?
