Some of my tomatoe plants are starting to look a little funky. Hear in central Oklahoma we have had a lot of rain. I am unsure if this is an over watering issue (Natual rainfall not irrigation) or some kind of issue. I was thinking maybe a fungal issue due to the increased moisture.

does anyone one have any advice?

Sorry the the photos are bad, I am away for work and my girlfriend sent me these pictures to show off our tomatoes. I noticed that the leafs looked bad, so I'd like to take steps to fixing the issue.
