It looks like cauliflower to me. The large leaves with the white veins going through them are identifiable as cauliflower leaves. If you want to keep them healthy, try separating them into separate pots. This will allow the roots to spread out and stop them fighting for space as they seem to be quite close together. Lots of fertiliser means you will recieve delicious cauliflowers when the plant flowers. GL.
