Transparent Spots (Dime Size or Larger) on Zucchini Leaves

Question

My zucchini has clear transparent spots all over the leaves – even the newly formed ones. There are no pests at this point. The zucchini right next to it is perfectly fine. How do I remedy this?

Answer 1

It is either fertilizer burn or some kind of insect or mite.

If you are fertilizing from overhead, either water soluble or granular, start applying straight to the soil. If this is not the case, treat the plant with both a pesticide and a mitecide. I personally like to use neem oil as it is both a pesticide and a mitecide, and is also organic. Here is more information on it:
