Tomato stems turn downwards
Hello, I am reposting this from the container forum since I was told I may be able to get help here. My tomato plant's stems are all pointing downwards and some of the leaves and stems have started wilting. This happened after 2 days of hard rain and then 2 sunny days. It's an Ace 55 plant and was originally in a 5 gallon pot. I've moved it into the ground now in case the pot was a problem. I've probably just stressed it out even more. Here are some pictures from a couple days ago.
I didn't notice any holes in the leaves or insects on it. I haven't sprayed any pesticide. Does anyone know what is happening to my plant? Thank you.
