As you "grow on" your seedlings you have to pay attention to moisture. It's recommended that you let the soil medium dry out in between waterings of impatiens. Here are the New Guinea growing on in their packs. Please notice that I have added some starter mix around the seedlings. They look like they are getting a good start.
Here's the basil, it's almost doing too good. I may have started that too soon. It may need some pruning before it can be set out.
