You seemed to be confusing.
Well first of all white magick isn't a group of magick spells etc., it is a type of magick, white magick refers to those magick eg, healing, health, etc, magick that does not hurt others are considered as white magick
black magick eg, curse, hex, magick that hurts others are bad, so it is considered as black magick.
Green magick, eg money spells or wealth, is considered to be green magick.
When we say green magick it doesn't mean we're doing healing magick coz healing is white magick.
So white magick elemental magick, it is up to you what kind of white magick do you want to do eg, healing.
and it seemed like you want to do elemental magick, well what kind of white magick do you want to do using the elements energy.
You are a member of the element magick coven, you can check good spells (healing spells etc) from your covens spellbook.
Blessed be. :)
