Cucumber problem

[Hist]

Hi guys. I noticed that all of my cucumber plants , regardless of where I plant them in the garden, develop a kind of “browning” of the leaves and eventually the whole thing dries out. I’ve tried watering a lot , for others watering little less, trying different things to see what the problem is but all of them end up like this eventually. Any idea what is wrong ?
As for pic 3 , Are the leaves looking okay ?

In the first picture it shows what appears to be a bacterial issue. What does the bottom of the leaves look like?

Do any of the leaves severely wilt on the plant and have you noticed any spotted cucumber beetles? If the answer is yes I would say your plants are infected with cucumber bacterial wilt. In the third picture you asked of the leaf looked OK. It looks like it has been attacked by a sucking insect such as a beetle. There are numerous spots on the leaf where it appears this has happened. If you have a badly wilted plant cut the plant off at soil level and squeeze the stem. If a gooey sticky substance comes out it is bacterial wilt.
If none of the above has happened the problem is probably fungal although I see no evidence of this. Neem Oil is a fungicide and insecticide so spraying with this would be an appropriate thing to do.

Oh damn. Now that I think back I do remember seeing some sort of beetle on my cucumber plant I didn’t think much of it and ignored it ‍ It makes sense now thank you so much for your help !
