Clematis Avalanche

We had a rather sickly looking Clematis on the summerhouse and as that needed painting I cut it right back earlier in the Spring.
It subsequently regrew and looked very healthy so we decided to let it grow and train it back on the summerhouse but keep it more compact and smaller.
It had been doing well but now I notice fairly significant browning of the leaves and a white discolouration to others. I think this is what is happening prior to the leaves dying. A couple of photos
The problem seems to be halfway along the various shoots. It looks healthy at the base and at the ends. Any ideas folks?
Aspect-wise it is SW facing do gets a good amount of sun.

Short of water Dave. Not uncommon but easily fixed
Give it a really thorough soaking and a mulch. It should recover no problem. It's an early flowering variety so dry summer weather in that aspect is not ideal for it. Don't let it get dried out and it should be fine.
I live in west central Scotland - not where that photo is...
Thanks FG will give that a go. It's in a small opening of the patio against the concrete base of the summerhouse and gets the hottest part of the day so that sounds very plausible! Many thanks
It looks like mildew Dave - common issue. Lack of water is the usual reason for clematis looking a bit ropey at this time of year
When they're very close up to a wall or fence, they get a bit sheltered from any rainfall too, so it's easy to forget that they could be a bit dry there.
Nice plant - the foliage is such a lovely shape

Yes, Dave, definitely powdery mildew ( not downy mildew ) caused usually by lack of moisture at the roots.
