7 Reasons Why Are My Zucchini Light Green
One possible reason your Zucchini is light green is that it may not have fully matured yet. I don’t need to tell you that young Zucchini plants tend to be lighter in green and gradually turn dark as they age or grow.
Generally, it would be best to harvest your Zucchini when it is 6 to 8 inches long with a deep green color. I have seen many people harvesting young zucchinis before they’ve even had a chance to mature fully. If this is the case, your Zucchini might appear lighter in color due to continuous harvesting before getting fully developed.
Another possible reason your light green Zucchini plant could be a nutrient deficiency. I have seen many people, especially beginners, provide imbalanced nutrients and fertilizers. Ensure to provide adequate nitrogen, Phosphorus, and potassium to grow your Zucchini plant healthy and strong.

After that, test your soil, or take a sample of the earth to get it tested in a lab to determine what nutrients it needs. I’ll highly advise you to consider using Epsom salt for Zucchini plant to improve nutrient intake.
As per the UGA, you should provide at least 160 pounds of nitrogen per acre yearly to produce a healthy crop. Hence, If your soil lacks essential nutrients, you will find your Zucchini plant struggling correctly. Thus it may end up being lighter in color.

Firstly I recommend you check what variety of Zucchini you have. Some zucchini plant varieties are known to produce yellow and pale green colors, like Caserta, Lebanese, etc.

Lastly, you should check the pH level of your soil because it can also impact the color of your Zucchini. I hope you already know that Zucchinis need a slightly acidic soil with a pH range between 6.0-7.5.
If your soil is too acidic or alkaline, it can affect your plant’s ability to absorb nutrients efficiently, ingimpacting its growth and color. Encyclopedia Britannica says that soil pH levels can also impact the severity of certain diseases like powdery mildew.
Therefore I recommend you first test your soil and determine its pH level. Sometimes adjusting the pH level of Zucchini plant soil does the work to restore your plant’s natural color.
