Clematis discoloured leaves?

Hello there
I have a clematis that was planted earlier in the year. It has grown a lot and flowered vigorously from the end of spring. Since most of the flowers faded however, the edges of many of the leaves have blackened (see below). I don't think this is clematis wilt as it hasn't come on quickly. Can anyone advise the best course of action? Many thanks.

 

I would put it down to the weather conditions. Not something to worry about.:thumb:

 

That's great. Will leave it alone then. thanks David.
