Judging by your photos and I hate to be a stickler but, those tricomes were definitely not ready for harvest. What you thought was amber was actually dirt that had gotten on the bud. Or often as myself as a new grower I used to mist water on the buds and keep my humidifier too close. So even the tiniest little leaf litter can make a tricome head turn brown. The key is not looking for brown itself but watching between week 7 and 9 of flower chosing a spot on the plant that is mostly clean and likely protected by a fan leaf around the center of the bud. All the tricomes should become milky over time. Then a few amber ones around week 8 or 9 some sativa dominate strains can go 10 weeks or more. Looking at the amber tricomes they should be full and hanging over just a little bit. If you look at your photos most are still clear and the brown ones are broken off or apart. Looking carefully you can see trash has gotten into the heads. A true amber will look like the rest milky alone the stem and amber translucent on top. Otherwise you did a great job your humidity doesn't really need to be any greater than 55%. The biggest thing with humidity is mostly a winter time issue as air is dry and cold. Plus humidity will also help you heat your home and breathing so it's a win win.
