Now! If the
roots are wrapping in circles around the container, loosen them up. You can do a lot to these roots and will be forgiven. Sometimes I've even cut them with a knife if the rootball is too dense, just redirect them from circling around and around.
For tomatoes, you want to put some of the stem below the new soil level. It's a strange plant that will easily send more roots out from the stem, makes a stronger plant, but you need an even deeper container.
The peppers might appreciate a warmer soil, but if you are still growing in the house, it will warm up quickly
enough.
Hooray for you for getting seedlings to flower. Enjoy that first fruit.
