Hi
@pitt1130! Here are some clues to make your own organic NPK amendment. Nitrogen: worm castings, bat guano, human urine diluted at 20:1. Phosphorous: boiled banana peels, bone and fish meals, rock dust. Potassium: banana peel, bat guano, fish meal, kelp, wood ash, compost. Hope this will help, let me know in the comments section if you need any further information. Happy growing! 👊
