Is this bacterial wilt? 📎⬇️

Got some pics from last year’s tomato plant I wanted to share to clarify whether I can plant in the same medium again this year. I grow tomatoes in pots and last year I had two long deep pots with tomatoes. One pot had tomatoes I grew from seed and the other one had ones I got as seedlings from the store (can’t remember as to why though, maybe the tomatoes I planted in that pot died early so I had to replace them but i cant remember anymore) anyways both tomatoes grew very vigorously and healthy. But then suddenly the store bought tomatoes in their separate pot wilted over night and died. First one then the other and then the third. The tomatoes in the other pot continued growing till the end of the season. I strongly suspect bacterial wilt but I am confused as to why my other plants have done well as my soil should all be cross contaminated due to using the same equipment and tools and sometimes even mixing the soil. If this really was bacterial wilt and the bacteria were introduced due to the store bought seedlings this should serve as a reminder to start your own plants if you are able to. What is your diagnosis? Do you have any advice? Where do you think it came from? Do you think it is cross contaminated but the bacteria haven’t attacked the plants in the other container yet but will do so this season? Any help and advice will be appreciated.
