Zucchini Turning Yellow
My zucchinis are not a dark green and they are very fat at the bottom. Now I have zucchinis that are turning yellow. They are not soft and they are not wilting. What could be the problem? Some of the leaves are yellow as well.

Yellowing is usually caused by a lack of Nitrogen, which can be helped by adding nitrogen-rich compost, lime, or manure.
