have I killed my tomatoes?

have I killed my tomatoes?

I'm in New York City and grow tomatoes in a lovely backyard garden. I usually grow them from seed, starting them inside in February and planting them outside in May. This year I had big, healthy, lovely tomato plants growing in pots under a full-spectrum light in my kitchen. They were growing in the seed-starting mix from Gardens Alive, which is made of worm castings and coir. I watered them very well and went out of town last Thursday. Someone else, not knowing they'd been watered, gave them a second thorough soaking on Saturday. I came back Sunday to find that some of them had wilted and collapsed, I think from some kind of root rot. The rest looked okay. This morning, I scooped out most of the waterlogged soil from each pot and replaced it with new, dry soil, hoping it would soak up the excess moisture from what was left. I'm wondering whether that is too little too late and whether there's something else I should do. Any input would be appreciated. Thanks!
