To me, it looks like some kind of bacterial wilt, or one of the fungus wilts. Is it affecting just some of your plants, or all of them?

I had one plant out of 25 do that this year too, at first I thought it wasn't getting enough water, but nope, and finally I removed it to avoid further problems.

it affect almost all of my plant.About 18 plants in a row.It happen the same to my watermelon too.
