Not to diminish ardesia's or Gina's advice, but just to say, only the very most inappropriate choice will be a certain death for most plants. And don't assume a set it and forget it mentality. As Gina said , you can adjust care to compensate for soil choice, to some extent.
Down the road, consider just buying a really top mix like ardesia suggested and don't play with individual components on your own, unless you find it fun to experiment.
