Or the better way to tell without guessing by someone else's crop is to get a good magnifying glass and look at your crystals up close. When 50% are amber colored she's ready. Hairs are not a good indicator nor is looks at pics of harvested bud. Once you have a good magnifier look around online for pics of ready to harvest trichs not the bud.
Hello, so lets talk about harvest...Normally we use a jewelers loop, These can be found at your local jewlery store or harbor freight. Now if ya dont have one you can look at the pistils the ones that look like a white hairs coming out of little bulbs known as calyxes. If these hairs look dried up and orangeish brown around 75% or more the window is closing for your girl. Normally you should start flushing when this first begins this color shift from white to amber on the PISTILS. Now if ya have a gotten your loop you can look carfully at trichome heads, when these cannabinoids are ripe they look milky not clear on the heads. When fully ripe they shouyld all be milky and about 75% amber heads. Peace let me know if ya got questions.
