Hi, Gracey: The puzzle here

Hi, Gracey: The puzzle here is that it is only one of your plants. It's possible that there is some sort of pest involved (see Pests above), so do some exploring of the dimples. Sometimes these can be the result of damage when the zukes are young, but this would not seem to apply. Another thing that can cause this is a quick temperature change that causes the moisture content near the skin to vary. But all the fruit on only one plant? Readers?
