What is up with my tomato leaves?

I checked the tomato problem solver linked in the bio and maybe this is early blight? It feels like it doesn’t match up with anything to a T (my hypothesis is I have two separate unidentified issues). This is my first year gardening. I have several cherry tomato plants and all of them are starting to have leaves turn yellow and some also turning super crispy, like brown and will shatter when touched. I live in south Louisiana and we’ve been getting a ton of flash floods over the past month or so and lately it’s been in the low 90s with 70-80% humidity. So definitely not idyllic weather. I’ve been pruning the damaged branches with the yellow and crispy leaves (some branches look normal with green leaves and I’m leaving those be). All of them are still setting fruit, though it’s slowed down, and the fruit are ripening with no visible signs of damage. I alternate spraying between BT and spinosad and feel like I have the destructive caterpillars under control (though this damage doesn’t feel like bug damage, at least to my knowledge). I try to fertilize between a mix of espoma fruit tone and neptunes harvest fish and seaweed liquid fertilizer. While most of the photos are from the same plant, the damage is similar across all of my plants. I do clean my pruners with isopropyl alcohol on a daily basis ( the powdery mildew on my melons won’t stay away so I’m trying to not spread it).

If anyone has any ideas on what’s going on and how I can help (and maybe I can’t 🤷‍♀️) that would be great.
