No discoloration on the leaves. The stem is healthy. The symptoms listed on this link is exactly whats happening to mine.

I'm no expert but the person in the other thread said it was the branches that were curling and twisting, the leaves being ok. Your picture looks it's the leaves that are curling, not the branches.

No the branches are curling also, but it seems like the plants are recovering again. Not sure what happened.

Thanks Mockapple! Positive feedback is always good when so much care went to these plants. They looked so good and all of sudden this curly branches. But they seem to be recovering. I would hate to lose them.

My neighbor has a commercial lawn service spray her yard a few times a year. Last year, the tomatoes near the fence that borders her yard, had branches that curled.

Hi Sumilea - leaf roll and curling stems are signs of physical stress on plants but usually correct themselves. It a normal response of the plant and once the plant adapts to the stressor or the source of the stress disappears so do the symptoms.

Transplanting, excess top growth vs. root development, too much fertilizer, excess water or inconsistent soil moisture levels, etc. - you name it ;) are all stressing factor and can result in unusual appearance. But it is almost always transient. So control the causes that you can control and trust the plant to take care of the rest with some time. ;)

If you haven't already, you'll want to do some for-future-benefit research on "leaf roll" as it is one of the common spring problems - lots of posts on it here.

Could also be 2-4-D poisoning.
Even a minute trace from a neighbor spraying weeds with an herbicide that contains 2-4-D will stress tomatoes and peppers....And sometime kill them. Search the web for 2-4-D and tomatoes.

From your pictures, these plants are still growing inside, right Sumilea? Thought so.
