Can I make my own nutrients

Watsup everyone? I have a question I am about two weeks into flowering and I am trying to find a fertilizer that is high in potassium, but i cant seem to find one. IIs there any way to make a fertilizer myself that is high in potassium? I have heard before you can use egg shells, is this true? any help is appreciated. I dont have a credit card or I would buy somthing online so let me know, thanks.

sure, won't do much good though. potassium is a difficult element to get from anything at home, molasses is the only thing that I can think of, tablespoon/gallon of water.

hey rodi, i add pure potassium to my nutrient mix, theres this stuff called Meta K from Earth Juice, and its just potassium, i also use thow whole line of GH and i add it through the plants whole cycle till flush time. its cheap too like 10 for a quart i think. the plants seem to love it... but if u cant order it or buy it from a hydro store.. then i dont know what to tell you
