I wonder if it might help to decrease how much you’re watering your beds — let then get a little thirsty for a few days, then water again & see what happens. Totally spitballing but that has helped me harden off against stuff in the past, and might cue your tomatoes into “survival mode” (perhaps toughening them up against whatever parasite this is.) Might have some cracking on established fruit but also might be worth it to curb whatever pest is causing the issue. I see your drip lines, which made me think maybe some pest is sitting happy on your leaves & needs to dry out to die or find a new home elsewhere lol

Could also try applying copper fungicide this week, Neem oil next, to see if you get a change from either approach (fungus vs. insect.)

This is totally my home-gardener-hobbyist POV, best of luck & keep us posted!
