There's a University text book you can get really cheap second hand called "Plant Propagation and Practices." If you read through the sections on the structure of flowering plants, herbaceous plants and olericulture, You will know more about cannabis cultivation than any youtuber, influencer, or cannabis themed company around. The internet is not a good resource, because most of the information is put out by seed companies, nutrient companies and purveyors of cheap grow lights. It's not all awful, but the fact is they don't exist to ensure that your plants are great and you produce lots of cannabis with very little effort. They exist to sell you their below commercial quality equipment, at an insane markup, when you can get identical, or better equipment from Alibaba. Advanced Nutrients has made an absolute killing splitting up N-P-K over and over again and selling it back to you at 300% mark up. The mermaid with the big tits on the bottle, isn't for the plant, it's for you!
