I would guess that is insect damage. I've never heard of a blight that attacks okra. I've seen similar damage on my okra and it had no impact on the plants. The lower leaves on okra die off as it grows. They don't last long.

Thank you! I used Sevin dust last week, but am scared to use it more than I should. I guess I shouldn't be concerned then? Here's another pic of my okra I was concerned with having blight. Dark spots.

This is on my tomato plants, in close vicinity to my okra. Blight? I'll be a monkey's uncle if I put in this hard work to let my plants die bc of something I can help/prevent/treat!

The okra issue looks physiological to me. I'd say it's sunburn in the first pic. Not sure about the second pic but could be an opportunistic fungus because the soil looks really soggy.

A few things I'd like to point out:
- the okra plants are too crowded. Okra can get huge if the weather cooperates. One per pot is sufficient.
- Don't use insecticides, particularly Sevin, unless you have a very good reason to use it, such as an uncontrollable infestation. Sevin should never be used as a preventative. It kills off beneficials, which sets you up for a future infestation.
-the tomato problem looks unrelated to the okra issue. I'd say that is blight but maybe a tomato expert could chime in.

Thank you! I had planned on thinning out tomorrow, but didn't know if my strongest plant had issues or not. Thank you for the feedback!
