Now some of my other vine plants seems to be exhibiting some of the same
signs that the peas did. I have pole beans, acorn squash and pumpkin that the
leaves are starting to turn brown on the edges. This browning starts with the
leaves at the very bottom and starts to work it's way up the plant.
Strangely, my onion, carrots, broccoli, collards, cabbage, lettuce and corn
appear to be fine. It seems to only be affecting vine plants.
What am I doing wrong?

Most likely from your description; Fusarium or pythium root rot. These are soil
borne diseases and a serious threat to peas and beans in particular. Soil Guard
(Gardens Alive) helps somewhat. Not much else available to the home gardener.
On a long term basis using a rye cover crop and or following a rotation of corn
decreases the population of pathegens.
