The leaves of the cucumber plant that is growing in my greenhouse are becoming quite yellow. Where have I gone wrong and how can I fix it. There are several baby cucumbers growing steadily

Thanks, I can try that. I can't actually see any mites though.

Unless your eyesight is very good, they are difficult to see. I'm afraid by the time I realised what it was I'd lost the plants.

I think you might have red spider mite. I have lost several plants over the years due to this. You need to keep the greenhouse humid by watering the ground frequently.
