Hi. For years, I have grown my tomatoes from seeds, and this year is no different. I have 65 plants that have been doing great. Last week, I repotted them to a bigger size pot. Nothing out of the ordinary...all of them still look fantastic...with the exception of 6 plants. The day after they were put into the new pots, they looked as though you took a pencil and twirled their stems around it. See photo. Curly and drooping stems. I thought they may recover, but its been about 4 or 5 days now and they still look the same. I'm baffled as to why these 6 plants reacted in this fashion while the rest are great... and they were all handled the same. Any ideas at all?
