FIM mean "Fuck I Missed"
FIM is an acronym for not topping the plant correctly.
Another side by side I'd like to see is flushing vs. not flushing before harvest. Same strain, grown at the same time, same nutes, etc. A nice objective look at look, taste, smell, and potency.
Molasses Vs. No Molasses as a finisher would be interesting.
coco/perlite hands down will kick the shit out of soil, 1000's as well trounce the 600's I have done both before and this is my valid honest opinion.
