This is the first time I've grown cucumbers in a container (homemade Earthtainer) and I was initially quite pleased with the results. My plants grew quite vigorously and I've been getting a few cucumbers each week.

For about 4 weeks though, I've been battling yellowing leaves. I've never seen any bugs but I have tried some suggested remedies for pests and disease. In the past week (4 or 5 days), I've noticed that the plants are not feeding; as soon as I put a hose in the fill tube, water starts flowing from the resevoir.

I have several fruit on the vines but they obviously can't get big enough to eat if the plants aren't feeding. Is there anything I can do to save these plants?

Thank you.
