I’m trying to make my own fertilizer and soil mix based on regular food waste, using coffee grounds(nitrogen), crushed bones(phosphorus), banana peels(pottasium), egg shells(calsium) etc. But I have no idea how much I should add of each per gallon/liter.
So lets say we have a 15l/4gallon bucket, how much of each element would you add to make a good cannabis soil, and what else would you add?
