Ah, okay, thanks for clarifying which succulent it is. With my epis, I just use schultz plus 10-15-10. But I am not too regular in doing it, to be honest. But if I do remember to do it, I apply it right after it blooms. I am more concerned keeping it in a moist condition, since it is too dry here, so easy to dry out with our bad humidity levels and no rain.
For me, it is hard to really quantify which is the best fertilizer, since our individual micro climates and growing habits varies.
But do wait for answers from others in a similar location as yours.
