Anyone else making their own fertilizers?

[Figarosmom]

I make banana peel water for potassium which helps make stronger fruits, veggies and flowers. And I go out in the alley and gather nettles to make nettle tea which is rich in nitrogen for good root , stem and leaf production. Really any weed cut up and cramed into a bucket with water and left to sit for a few weeks makes a good concentration fertilizer . Has to be watered down like 10/ 1, 10 parts water to 1 part concentration. It really smells though so keep it covered.
