I'm looking for liquid ferts, Potassium, Nitrogen, and Phosphorus to be exact. As it so happens, none of the LFS in my area carry any of them. They only carry Excel Fluorish Supplement.
So anyhoo, I was wondering if there's a way to DIY the ferts. Where would one get the ingredients needed for these ferts?
