It's easy to overthink harvesting. It is the most important step of the whole grow in a lot of ways but if you made it seven or eight weeks with my strains, you're gonna have some good weed regardless. They are going to yell at you for not taking pictures perfectly in the center of the bud and that you took pictures of the sugar leaves and it's not an accurate reading, blah blah blah blah blah I think you're getting close dude Trust your nose and make sure you don't have a bunch of under developed stuff down below. I'd say you have a week or two left judging at the color of the hairs (stigmas) And the spectrum of colors im seeing in the heads. There's a few Amber there and some clears I don't really see any milky. I personally start harvesting once I start seeing any amber. The amber color of the tri-comb isn't indicating a change of chemistry in the Tricom head. It's merely showing that the Oxidation has occurred. Undeveloped tri-combs can become oxidized to. The reason I harvest when I see Amber is because it tells me the plans shutting down. I don't think that milky tricombs always means peak. Harvesting is personal preference to. Some people like harvest when the bud is practically about to rot it seems like.
