It doesn't help that some people try these products and go "WOW! Best shit I ever used! My plants look great!" Uh huh. Look great compared to what? did you do a side by side grow at least, one using one with and one without, minimum? People want to believe in the positive and don't take the time to examine things in a neutral, critical, manner, when they should be saying, maybe, we'll see.
I wish I had the setup and the legal ability to grow enough plants to really do some side by side testing of stuff like these supplements. Lighting comparisons (blurple LED vs COB LED, etc..etc), soil comparisons, etc..etc..
Basically would love to just have two exactly same setup tents side by side to grow out maybe half a dozen clones at a time from a couple different mothers in side by side comparison setup. Make vid's and journals and post the results up. Etc..etc
Would be a fun way to really go overboard with the hobby.
