Dude I totally recommend natural nutes exactly like compost.

I live in a region of the US where there is a very deeeeeep knowledge of this stuff. I myself am a newbie, but just try to soak up the knowledge from the old- schoolers. The OG growers actually make their own soil using exactly what you said. The real mind- boggler is wrapping your mind about soil nutrients and soil needs. I am taking on online class right not on sustainable soil management to get a better concept of what soil needs most.

My opinion based on what I see is that building your own shit is the best way to go long- term. Fertilizers are only ideal for one- off projects and people who are in it for the money money money!

Established growers who are environmentally conscious build their soils with cow manure, chicken poop, food scraps, etc.... and constantly monitor these compost piles but keep them ideal. An example is that adding too much cow manure can make the soil have too much nitrogen, and go "hot" which isn't cool for soil equilibrium.

Fertilizers are the quick and easy way.

Personally, and to be honest, if you are new use the fertilizers and get to know growers who do their own soil. And take classes on soil biology if you are into that groove as well. Thanks a bunch! Big Love from Oregon.
