Has anyone ever experienced ozone damage to their pumpkin plant/vine? I have one vine that has white damage of some sort. It doesn't look like mildew. It looks like white marks that are webbing throughout the leafs. I have sprayed it with baking soda/H20 mixture but that hasn't seem to make any difference. There is not much information on the internet about ozone damage and what it looks like on pumpkin plants, but from what little info I have found, it sounds like that might be my issue. I have attached a picture (hopefully it attaches successfully!). Can anyone help me diagnose this issue? And should I cut the vine immediately? I would really hate to do that because there are a few pumpkins on this vine that look good, but I would also hate for it to damage other vines, plants, or sections of my garden.
