Cucumber disease identification

[bethanysavannah]

Hi, wondering if anybody has any clues to what cucumber disease this may be... Based in the Lake District UK. Some of the fruits themselves have been affected in flavour - mostly bitter flavour. Doesn't seem to be any effect to the stems themselves just the leaves, fruit and flowers. Some gold gum was found on fruit and a tiny bit on the outside of some of the stems but nothing when stem is cut open.

looks like a form of blight.., had similar on my courgette plants.

hmm, this is what i was thinking as it shows no real sign of downy mildew.

Looks like blight to me - I know nothing of cucumbers but reminds me of potato blight

If it is 'gummy' then it is perhaps Cucumber scab- Cladosporium cucumerinum

Virus if spread from one or several plants.. No sign of fungal pathogens; pale/yellow edges to discrete mould patches or rot lesions. If all plants affected at once however consider environmental effects. Cold, <12C sends cucs backwards fast.

Doesn't look like red spider mite but check beneath leaves with hand lens.
