It's the cat piss smell/taste. My 3BOG was strong with it all through it's grow, thoroughly checked before breaking down and putting in grove bag. Hygrometer staying in the 60% area and nothing creeping on em.....I just really hate the smell.
...nothing to do with your feeds mate! As you likely know, there's several "cat pee" type cultivars out there
by name, and plenty of others that may express this profile like Trainwreck (I grew that hoping for what I used to get decades ago in that stank)...
I know it's not for everybody! It's the jar smell typically, I found it not to be in the smoke though... Room smoke aroma was amazing, like exotic incense. Something about the combustion process...
I also found that more floral aromas come out when ground. vs jar aroma...
The Twenty20Mendo TW I grew last year was close to full cat pee, a common pheno in their well preserved cut of it... Mine was more piney-citrus, alas -
It sounds like yours was a real obnoxious variant, and really rare in a 3BOG...
I get the let-down though, had aroma profiles in other things that so not to my liking...
