Trichomes are where it's at. Don't worry so much about weight. Bud mass is largely plant matter. It's the frosty coating we're really after :D
Just my opinion but don't fret not starting more nutes earlier. That's always the temptation when things go well, we think "but just a bit more would have been even better". You don't know how things would have gone differently if you had loaded her up sooner. It may not have been such a stellar outcome, we can't know that. I'd be very happy with how it's turned out and not plan to go heavier on the products next time.
Love the closeups of those flowers and trichomes! Naughty pets are getting their hairs involved though.
Congrats on the $40 post! Things are looking up on Hive!
