Hey!
It's AK 47's 50th day from flip to 12/12.
There are just few amber trichs. I'd like to harvest them asap without diminishing yield. When would that be?
Get yourself a pocket microscope w/LED or jewelers loupe w/LED and wait until you see 10%-15% amber over all the plant, that would be an ideal time to harvest.
Also, the last few weeks of flower the buds can swell up and add a lot of weight, so be patient.
I see shiny little convex leaves, plus she looks as if she is about to foxtail, which looks good, but is fairly uneconomical. Hard to judge on one cola.
This sounds perfect to me. I also am about to harvest AK-47... and I have them on the calendar as between 53-63 days... sounds like you are right in there.
