black/greyish spots on my japanese honeysuckle

Hi!
I bought a few evergreen japanese honesuckle plants in June and although they are growing at a healthy rate, one plant has a few yellow leaves near the bottom and middle area, and today I noticed that there are some black/greyish spots on a lot of the leaves. Can you please tell me what I'm doing wrong, or how I can correct these problems?
Janet

 

It's a type of mildew japanese honeysuckle is prone to it the damp weather doesn't help you are doing nothing wrong,the leaves will fall off but they will regrow.

 

Hello Walnut,

Kind regards
Janet
