Hello
Ooooo wheee those are some good photos thank you for that. I personally like mine to be about 20% amber, but I usually go off the vibe from each individual plant, some I've harvested with less amber and some with more. But I don't like to get anxious weed so i usually wait till i at least don't see much glassy ones...dominantly milky and then evaluate the amber.
Yours looks like it has passed the 20% marker...if it was my plant, I'd be doing a mild flush and cutting her down here very soon....within the next week.
Happy harvesting. โ๏ธ
