What do you think is up with these?
It’s been very hot here lately, almost 40C, and we have had two storms in 4 days and a fair amount of rain. The plants are all 3 feet apart, they were pruned two days ago and no sign of this. Mainly just one tomato plant and one bean plant are affected. Only a couple leaves like this on a couple other tomato plants. I live in a VERY windy area, so lots of airflow and breeze.
The leave tips look soggy, then just crisp up and dry.
There’s no blackening or anything on any of the stems and all my plants are supper healthy other than a bit of leaf curl.
My first thought was blight (which I had when I was living in the city), but it wasn’t quite like this. The stems had black spots, there was black spots on the leaves and spots on the fruit and the plants themselves were very unhealthy looking by the time I noticed anything was wrong. This isn’t like that at all.
Could this be from the weather?
I’ve also been sprinkling diatomaceous earth on them.

I won’t say so definitively — it’s hard to tell even from close-up photos — maybe show us one of overall view? But from what I can see, other parts of those plants look healthy. I can’t see if there is a more widespread / generalized or swath of damage like from accidental spray or splashing of damaging liquid (maybe containing oil or chemicals or concentrated salt) — some of the leaftips and blots could be dropping pooled liquid on leaf edges or dimpled wrinkles in the leaf.
But if some of the cells / areas of those leaves were damaged — and really only you could tell from things around them and which way the leaves might have been whipped around or sprayed/splashed on — those areas would then be susceptible to sunburn as you had surmised.
It would be like if you had blisters / scrapes / wounds and got some extra sun, and the damaged areas of the skin burned while other healthy skin didn’t.

Some of your tomato plant leaves look like sun burn. I have seen my tomato leaves do that in hot weather. 40C = 104F. Leaves in full sun get much hotter than the air temperature. Did you ever notice hood of your car gets too hot to touch in full sun in summer. I read online leaves can get 30 degrees F hotter than the air temperature. If you have a laser thermometer check leaf temperature hottest time of the day.
My garden tomatoes are sun burn it has been 98 degree F here, several leaves are, brown, crispy & dead. I squirt muddy water on my tomatoes to block the sun. 50% dead leaves won't hurt anything.

Rough history — discovered and named for mischievous, tomato-loving dog named “Girl Girl” who repeatedly stole ripe fruits from one particular plant in the garden. Seeds saved and subsequent offsprings grown in succession to stable segregate line. Currently slight variations exist among available seeds, so need to find source with line that is true to intended characteristics.TomatoNut95 wrote: ↑Tue Jul 21, 2020 1:13 pmI'm getting curious myself...

I'm keeping my fingers crossed it’s that. It has been ridiculously hot and that spot gets a hell of a lot of sun.

The one that was affected most is an anomaly. With the leaf it’s supposed to be PBTD, but none of the tomatoes have stripes and the shape is almost heart shaped. So we will see.
True Black Brandywine? I thought of getting that variety. How's it like? Meaty? Sweet? Prolific?

they’re one of my favourites. Very sweet and meaty, slightly acidic, well balanced I think. This is my third year in a row growing them.
I grow them mainly for salads and sandwiches. I normally have at least 5 varieties, but we moved and I couldn’t find all my seeds. A family favourite is Feurwerk which I’m bummed I couldn’t find. They’re my husbands favourite and I’ve grown them for about 7 years. That’s what’s in my avatar.

What's the Black Brandywine like?

TomatoGirl, I have Feurwerk seeds saved from the ones you sent me! I really liked them, too. I'd be happy to send some to you. Obviously too late for this year, but at least you'll have some for 2021.
I hope the rest of your crop turns out okay. I don't think I've ever seen that kind of black leaf burn (or whatever it is.) I agree that it otherwise looks pretty healthy. This weather has been nuts.
Best of luck.

That’s awesome. They’re delicious aren’t they?
Thanks for the offer. I’m sure by next year I’d have unpacked enough (hopefully) to find them if not I’ll let you know. Thanks so much!
