I have posted a pic of the tip of the main vine of my 681 Gansert plant.
The leaves are smaller than they should be and have an unusual cupped appearance.
So I am asking for some opinions from experienced growers.
I don’t think it is sunburn. Could it be disease or nutrient deficiency?
I had a tissue test 3 weeks ago that showed low Cu & I addressed that with Copper sulfate both foliar and through my driptape system.
Finally, could it be spray damage?
I certainly have not sprayed it intentionally but I could have accidentally .
I really appreciate any & all input.

My first thought was sunburn. I'll be interested to see what anyone else thinks.

I have attributed similar appearance to glyphosate residue. But it could just be nutrition imbalance or roots/ xylem issue.

Looks like spray damage to me. Possibly too much too soon. I have a very late planted field pumpkin doing similar thing after hitting it with fungicides.

I am wrapping the main vine around the periphery of my patch so it is possible that I inadvertently nailed it with a spray.
I will have to watch that when I spray.
