Just jumping in to reinforce above two excellent sets of instructions. I too augment all potting soil to create WAY better drainage. Even here in my arid climate, that is the key to allowing complete root zone saturation while preventing root rot.
What you said above: "This morning, I used a spray bottle to mist all of the soil again as evenly as I could."...
No, spraying the top layer is not watering. Pour the water in the way Humboldt described.
