Why are my cherry tomatoes splitting? I am adding a teaspoon of calcium nitrate once week. I’m using an earth box.

This has everything to do with environment. This happens when it is suddenly watered after it is too dry, or not humid, and the soil is dry.
Try to keep the soil consistently moist with only a slight dry out between waterings. Spraying in the early morning can help, as well.
