thanks for taking a look!

I first noticed the leaf problem a few weeks ago. Then a Squash the size of a small apple rotted on the vine. A few days later I noticed the baby squashes black & lifeless.

I have/had late blight on my tomatoes. .

second pic of the leaves; sorry about the fuzzy focus.

eta;
I've been examining the pic's here

To my untrained eye my problems don't look like any of the pictures...
I'm not having a problem with pollination, my summer sq, beans & cukes are producing like crazy.
eta again; I'm thinking there's two things going on, a fungus/bacterial issue & bug problem.

Are you seeing male and female flowers? I think the problem with the first pick is it didn't get pollinated. If not pollinated, it'll abort and die.

Definitely have a bug problem going on with the half eaten leaves. Do you see anything on the underneath sides of the leaves?

yeah, only the female flowers are effected. That pic is of a female flower, all the rest are just like that. All the male flowers are fine. Plus all my cuks, sum sq, beans peas are over producing. I'm thinking a fungus. I'm gonna spray with a antifungle & see what happens.

I haven's seen a bug but I'm notorius at not finding bugs......

ALL your females did that? The flower in your photo looks like it never opened, so it can't be a pollination problem, and as you say, your other cucurbits are doing well, so the bees are doing their job.

Yeah, all the small female flowers are currently doing that. I've gotten 3 squashes before the illness started occuring. I did have 4 squashes but when the 4th was the size of an apple it rotted. No dark spots, just kinda withered & became opaque.
