I brought it up to a few buddies of mine that this is a huge alert on the mmj communities online to not use these fertilizers. I even did some craigslisting the other day and found some guy selling off all his nutrients and a few of them are ones that contain these harmful chemicals. One being Humbolt countys gravity. It scares me to see that people around me have been using some of these nutrients. None of my buddies really have much to say about it all, but it kinda worries me.
