I can answer this one. A good portion of the information I've been told I'm wrong on and what I've seen other users called out on is the information we find when we Google problems or information about growing cannabis. Sadly there is a lot of misinformation because most of us have been growing for a very short amount of time and don't all have a good understanding of plant biology nor have had the privilege of taking educational courses for it/having been growing for a really long time and have had time to perfect the art.
The knowledge growers like you and
@RM3 have doesn't seem as readily available to the common user. Now I know if I search hard enough I can find information relating to how the pros grow and I can truly understand it. But the average user on here isn't going to read the skinny on a scientific journal on alcohol fermentation in plants they're just trying to figure out why the hell a pro is boiling their roots and they don't have the mind to connect the two together. That is the most sense I can make of it. I know I'm very assertive in my knowledge but I do admit I a newbie still and that is my "smart" newbie perspective.
Edit: Forgot to include that obviously because cannabis is still federally illegal we only have a few quality written resources that most new users haven't bothered themselves with (growing books you can buy online, etc.) I'm sure as times change and the attitude on the plant changes we'll see even more well established, publicly accessible, and 100% scientifically accurate books and materials that are easily understood by the common man.
