Cucumber Leaf - White Patch, Not Powdery Mildew

[Mr FootOfDavros]

Just wondering if anyone knew what this on the bottom of the middle plant there:-

Not sure if it's just some sun "burning" / discoloration maybe as I can't get these out yet and there just sitting by a window which gets a lot of daylight?

But I don't think it's mildew as the one cucumber I did last year, did eventually lose its leaves (and eventually its life, RIP) to that...

As ever, grateful for any thoughts. Thanks.

Water or feed damage?

Thanks. Do you mean water being dropped on the leaf during watering and then getting scorched in?

If so, maybe could be that.

Sorry, yes a bit watering spillage , very minor.
