I'm not sure what the problem is. It's only this one bush which is in a row of about 8 or 9 hydrangea bushes. All the others seem to be healthy.
The only symptoms are that some leafs have turned brown and there is this strange what stuff on a few of the green leafs. Links to pictures are below.

This is the plant directly next to the one is the above 3 images. It doesn't look as sick but there are some eaten leafs. Thought I'd post a picture for reference just in case.

Many thanks if anyone had some advice.
