Keep it simple...pro mix, castings, lime(CaCO3)NOT DOLO, rock dust (any sort).
Don't need a 16 long ingredient list...but now add your meals:
kelp, bone, blood,
kelp, fish, crustaceon
kelp, crustaceon, guano
kelp, neem, fish bone
My main point is keep it simple. You need the top ingredients, and a combination of at least 3 bottom ingredients.
Going more than that in my opinion is getting fancy. Especially just to get your feet wet!
But screw the soil and soil list.Really if you want to try organics, start up a worm bin. These castings are where you will get absolutely fantastic results. Regardless of your ingredient list.
