Pole Bean, Squash, and Pepper plants- Are they diseased?

[organic_veronica]

Hi all,

I'm new to gardening and see what appears to be leaf disease on my squash and pole beans. I also see some sort of vine disease on my pepper plant.

Squash- Leaves turning yellow, some look burned/brown, a few just look dead!

Pole beans- leaves have holes, and there are some brownish-gray spots where the texture is different than that of the leaf texture. A few leaves look dead.

Peppers- black on nodes.

Are any of these normal? [/img]

Yes actually the dark color around the nodes on the pepper plants is normal. There was a previous thread about this that has some pictures to show it:

So one less thing to worry about. The others not so much, but pictures would help.
