Cucumber help please

[darcyvuqua]

I only shaded half the greenhouse the lower set of glass have no shading and the leaves affected are close to the glass they are also by the door so get the wind too also the door when open exposes the leaves to direct sun light

No shading in pic could be severe sun scald in this weather. I have lost a few leaves of mine to the same thing.

It picked up nicely when I eventually remembered to shade it, cumbers don't like full sun.

The more I think of it the more this is what I think it is as the growth that's in the shading is all deep green
