If i taught you how to judge trichs like a pro then yes they are the most accurate way but a pro nay needs to look at trichs to know the exact second the bud is at peak dankness and should be harvested so rarely will he bother.
Peeps write a lot of stuff that is apparently so simple but then instantly they are confused.....
I’m starting Week 5 of flower.. have been feeding Tiger bloom, bud candy and just cal-mag until 2 days ago I gave the first dose of Cha-aching which is high is P and K. Seems like the girls LOVED it, they’re noticeably fatter after just 2 days from the first dose of it. It’s all about the lights and what you’re feeding it broseph
