Soil help

Hello, I have a few succulents and I’ve never changed the soil in the pots they’ve come with. My Jade roots is coming out of the pot so I will need to repot it soon.

I don’t have much available in my area, this is what I’ve found, I’ve been fertilizing with 20-20-20 along with all my other plants, however don’t have an issue buying a specific fertilizer balance.

Also don’t mind making my own succulent soil but need guidance. Everything I’ve read says loamy sand + compost or loamy sand + perlit but on all the videos I see these rock type soils used instead. I live somewhere dry and all my succulents live outdoors year round.

Any help appreciated!
