I have 2 cucumber in my greenhouse, they are growing really well, and we have had a couple of cucumbers of one of them, however, as they are producing new ones these are turning brown, also some that start off looking ok, then turn brown and in the middle (see attached photo of one). The leaves did start to have some small white powdery spots on them, which I took off or wiped down. I googled the problem for the leaves and one suggestion was to spray with 1 part milk to 2 parts water, which I have now done so waiting to see what happens.
Any help appreciated.
