Look in to promix, it is a good substrate that only contains starter nutes and is really easy to work with.
soil is fine so long as you know what you are getting in to. It takes a lot of flushing to keep the salts washed out. I just like promix because the plant gets what you feed it and that is all. Just like hydro except you are still watering what looks like soil. Basically a good place to start if you are considering hydro.
