That looks like some kind of herbicide damage. Any kind of spraying nearby?? I would at least chop off the bad part and see if the plant regrows normally, or you could replace. It's up to you.

2, 4-D damage?

Has anyone sprayed your lawn -- or perhaps the neighbor's lawn beyond the fence?

We have an organic garden and yard. No herbicides in our yard. I'll check with neighbors, but I don't think they have lawn on other side of fence. Could over- or under-watering do this? We watered every other day while plants were getting established. Thanks.

Sorry but that is a classic pic of herbicide damage. It could be in your mulch or any purchased compost, anything. But the most likely cause is drift and drift can be from as much as a 1/2 to 1 mile away depending on the wind direction and speed.

Every year at this time we see numerous posts of pictures of herbicide damaged plants. The source is difficult to tract but possible and it almost always turns out to be neighbor or lawn care service. Many have gotten damages paid.

Sometimes the plants will recover if it was drift or as mentioned you can cut off the damaged top and, if indeterminates, new growth will sprout.

Good luck.

It does look like herbicide damage but cold over nite temps and not enuff water could be a problem too. The bottom leaves (they look fine) make me think it may be in need of water.

Nutrients (& water) in the soil would reach the lower leaves first. Stick a finger into the soil a foot or more away from the plant stem to check for moisture.

Cover the plants when overnite temps are below 50.

How long have these plants been in the ground?

What kind of watering do you do? From the top? Soaker hoses? Water cans?

I use buckets with a hole drilled in them for deep watering.

It is not lack of water. It looks like herbicide damage to me too. And my experience says that even though it may grow out of it at some point, they never truly grow and produce correctly after this. Sometimes you will see creamy white streaks on the effected leaves.
The stretching of the internodes of the plants is another classic symptom that is associated with a lot of herbicides.
Again, based on my own experience, I would discard them.
