The vegetables are still alive. Put some high phosphate ferlizer [bone meal] on the peppers yesterday with a pinch on the tomatoes and squash between the rain showers.
A couple days ago I had filled one of the 4 1/2" pots with potting mix i had sifted and started some lettuce seeds in it. Looked at it yesterday and it had fungus mold growing on top. The saved pots could have been contaminated so I threw all the saved pots and the one I had started the seed in into the trash bin.
