Could be genetic maby?. perhaps the seed you used was crossed with another variety, so its a F1 hybrid gone bad. I dont know just throwing an idea.

The first picture looks like herbicide damage, RoundUp or other.

Has anyone within 100 feet been trying to kill weeds with a spray? Anybody near you had their lawn treated? It can drift even in balmy breezes and really ruin other plants.

You've checked for insects such as aphids? One year my pepper leaves curled up because of them, but you probably would have noticed them since their numbers would have to be pretty great to cause that damage.

Maybe others can suggest other possibilities, too.

I see similar leaves every year and do not know what causes them. My plants seem to get affected after a sharp drop in temperature after some very hot days. They always continue to grow and produce. The weird leaves may only last for 1 or 2 branches then return to normal. As the deformed leaves grow in size they often get more and more normal looking. Acid rain? Air polution? Herbicide drift? I don't know but I think you will still get tomatoes, at least I did for the last 3 years with plants that developed leaves like the ones you posted.

The first pic looks like what happened to some of my tomatoes last year. It was determined that it was herbicide drift damage. They survived and produced.

I agree with anney & opie. A flushing of the soil with plenty of water and some heat/sunlight would do that plant well. Maybe a diluted water-based fertilizer after the flush.

I've read that air pollutants, such as carbon monoxide, can cause symptoms like these in leaves. Might be worth looking into..?

As has been said, herbicide drift.

Yea...something for sure just attacked that plant via air travel. What it is, you must find out.

My husband sprayed grass killer (Grass-B-Gon) in a nearby flower bed, but that is supposed to only effect grasses and not dicots. I suppose one of the neighbors could have sprayed a weed killer. Do you think they will survive?

That stuff is purported to kill all plants it comes in contact with, though I suppose it's all relative. IOW, it might just damage the plant instead of killing it if the drift was very light.

Anyway, I think all you can do now is wait and see if the plant develops healthy new growth. And don't spray it or any other herbicide around vegetables again without heavily protecting them, no matter WHAT the company hype about them says.
