I'm not trashing your methods, but when I started growing weed I thought it needed to be treated differently to all the other plants in the garden. I fell into the same trap as when I started growing hot peppers. Cannabis specific soils, cannabis specific nutrients, special blends, etc.
I learned differently. I think the best advice for new growers is to keep it simple until you have some experience, then start experimenting a little until you find what works best for you.
Thanks for the post, it fuels discussion if nothing else, and makes us all think about our own methods. Questioning our own assumptions doesn't happen nearly enough.
