Can someone help me understand why my tomato plants are doing this?
To me seems like too much sun and a nutrient problem.
Here, fields of tomatoes grown in full sun (dawn to dusk) get to looking like yours (almost) shortly after peak production. I've tried growing in full sun, too: results were pathetic (low production, lots of dried out leaves and these crispy critters ended my tomato season early) and I never did it again. I make it a point to grow in locations that my house or nearby trees provided shade after a maximum of 10 hours of sun. Problem solved: my tomato plants reward me for this respite with more production and longer!
Check out this link for nutrients- has helpful pictures.

The leaves that ARE green appear to be a light green. The magnesium atom is at the center of the photosynthesis molecule; it is a minor nutrient (needed in very small amounts) and is usually present at sufficient levels in the soil. since I grow both in ground and in containers, I use an Epsom Salts solution at 3 growth points: at transplant (using it to water in),@ first flowering and @ fruit set (lightly spritzing leaves).. . . in addition to whenever also the plants seem to need it!
UNPERFUMED Epsom Salts Solution: 1 tablespoon per gallon of water
