Gray Splotches/Discoloration on my Grapes
I have a young grape vine that I just planted about a month ago. I've recently noticed that it's developing graying splotchy patches on the fruit itself. When I went to the gardener, I noticed that their grapes also had these gray splotches.
Does anyone know what the cause is of these gray patches/spots? Also, is this normal? Is there anything that I can do to prevent it?
And is it going to affect the fruit itself in any way? (growth or taste-wise?)
