The bottom center of the picture is not too clear and that is what my eyes fixated on. There are times when the flower buds will produce reddish leaf sepal growth due to temp changes in the Fall so those would not necessarily bother me. The witches-like broom is what I was trying to make out but the growth at the bottom of the picture was difficult to make out, which may be bad news; things appeared too jumbled and up close to the camera in there so I could not comment safely.
Can you post a picture of that area from about 3-4" further away.
I know of your concern first hand. My sister mentioned she was having problems and it turned out to be RRD. However, she did not mention it for God, almost a year maybe!?! so by then, I had to tell her to pull the plants out so the other shrubs would not catch it.
