Q.Why Have Leaves On Cucumber Turned Yellow And Papery
Plants were vigorous and covered in flowers. The leaves suddenly turned yellow and papery starting at the bottom. Fruit have failed to set. I keep them damp and misted and fed. I have used tomato feed but then sprayed with seaweed folia feed but nothing has worked. Cant find anything in my books.

Unfortunately, this is likely an infection. This happens when the soil is not allowed to dry out, thoroughly, down to about 2 inches between waterings. Unfortunately, the damp, and humid conditions have caused disease to take over.
I would treat the area between planting, then try again. You may need a moisture meter to help you to determine when to water.
