Yellow Cucumbers

the cucumbers were growing great now they have slowed do and turned from green to yellow but thay are not full size yet. they still have a fat top and a small bottom. may leaves are turning yellow?? My first time in many years for growing these.

Could be you are over watering your plants. This happened to me one year.

Usually when the cucumbers turn yellow it is because they have been on the vine too long. Which makes the plant quit producing cucumbers.

What I would do is pick all the cucumbers that are turning yellow and see if you can encourage the plant to set on new cucumbers.
