I followed those nightmare threads. I am a new grower that just wants an easy inexpensive grow. I'm also cursed with an engineering brain with ADD, so some topics make me want to do a deep dive like I'm in the Marianna trench looking for new species. What I have been unable to find is, what makes one synthetic fertilizer safe and another not. Are there sources/types of minerals you look for on a label that make you avoid them like its a spider mite that just wants to crash at your place for 1 night? For instance, at one point in said thread, somebody said get that petroleum shit out of here(something along those lines). What is it that he sees on a label that makes him say that? I understand that some sources may be more bio-available, but am more interested in differences that may lead to someone not smoking bud made with one synthetic fertilizer but smoking another made from a different synthetic for health reasons. Not just because they think so but because of some verifiable reason backed with evidence. Not sure if this information exists. If you don't know the answer please don't just tell me to go organic if I am worried about it - I am not worried about it, I just want to know. Of course I had to make a spreadsheet. Thanks for any input!
