Get a cheap soil testing kit that can tell you levels of NPK in your soil, and adjust from there. Cannabis is quite beneficial for most any soil it grows in. You can always flush out the salts from the soil as well before re-amending with whatever yhou choose.
Yes, it's all about keeping the soil balanced and happy. Most people do not, and by the end of the grow it's too far out of balance and they just chuck it and buy more. If you do it right, it never needs to be flushed either.

When you learn to take care of the dirt, all these ($$$) fungus and bacterial additives become pretty funny... not only do people spend cash on new dirt, which isn't nearly as good as old dirt, but they are throwing out all these beneficial microbes in the old dirt too, only to pay lots of $$$ on these additives to re-introduce them. In my experience, the first run on new dirt isn't as good as subsequent runs, whether you use these ammendments or not.

There is also no reason to spend lots of $$$ on "high end" nutes, although I do use liquid ferts in the water at every watering. In general, they are only used at fairly low levels to fine-tune things.
