Hello,
Is anyone here familiar with this leaf disease that got one of my potatoes and one of my squashes.
I thought maybe blight but i am unsure.

Thanks

Hiya,
That’s not blight and squashes don’t get blight - from a veg perspective this is generally only seen in the potato family, particularly spuds and tomatoes.
Could it be cold damage?

Maybe, there were a couple of cold nights that took me by surprise.
