@Jim Mat - I thought about this and it does look like it. However, they're not in the sun all day. They are shaded. I will look more into this. Thank you!

@albert_135 will they live and become healthy and productive or should I replant new ones. We have not put anything on them except water. I did use garden soil from lowes. It just bizarre because all of them have the same symptoms. Some are in the shade more than others.

Did you have a light frost? One of mine looks like that I that's what I attributed it to. Now I'm not sure.

@Lynn Marie No, it's been chilly a few days but no frost since we planted. We planted them about 2 weeks ago. I think the two posters are spot on when they said sunburn. I've looked at a lot of pictures and that's what it looks like. Also, I remember I had some other outdoor plants last year and they had some insects. Well, I sprayed them with Neem oil which worked. However, I didn't know I should have done it early in the morning or evening because it can burn the plants during the day. I now recall the plant leaves looking similar to this. I have no idea what I'm going to do yet because the top of the plants are healthy and growing. I keep a close eye on the weather and UV because I'm often outside. I wouldn't say it's hotter but the UV is much higher. I have friends who have UV meters and they are recording UV indexes much higher than what's being reported on the news. I started looking into for months and sure enough, there is people all over the world reporting the same thing. And that research landed me into looking into the mass die off of trees, animals, and sea life around the world. I'm clueless to what's going on or what this means or why it's happening. It's disturbing though. I may keep a couple of them and replant the others. I have many pepper plants and they are doing well. My cucumber plant isn't looking so hot so I may ask about it. I'm no expert on gardening but I hope this helps. You would think I would know since my dad has been a farmer his whole life.

I'm in Temple and mine are looking OK. Nothing but water so far. They were in full sun MOST of the day in that driveway out back. But we carry the three plants inside when 40º at night was predicted recently just to be safe. Maybe temperature drop did this?

I just went though something that looked just like this. Turned out to be spray damage, from improperly mixed fungicide. Environmental damage, as noted. Not sunburn, because the plant shown only shows the effect on lower leaves. Frost damage looks totally different. Lower-leaves only might be a fungus issue, but I'm skeptical of that early in the season. The fact that most of at least the plant pictured looks fine, and assuming that it continues to look fine, suggests that the plant will end up doing well. Chop off the affected stem, and dispose of, and move on.

Every year I mix epsom salts and ground up tums ( calcium) in a gallon of water and spray my tomato plants thoroughly 2 to 3 times during the growing season. This seems to supplement regular fertilizers. If this is going to help you will see immediate results.

marymonkartist I cut the leaves off a while back and they took off. They seem to be doing well. Now if the heat doesn't cause problems, I think the plants will do well. Thanks!
