So yeah, could I use a pot and soil that was previously used for growing a plant that turned out to be a male, to plant a clone from a female in? Or will it fertilize the female?
That does not matter as you don't want to reuse it because the soil has the nutrition deapleted and also more bacteria and other shit you don't want is in that soil. Just go buy a new bag of soil.
