Hey Clump! Firstly congrats on a first harvest, and getting this far! Personally I go by stem snap, not just in one place, but a couple of snaps give me a good indication of how things are progressing. In time, and with enough experience, this method becomes quite reliable. Your drying temp range dips a bit, and without knowing how much of that time is spent on the lower range, its hard to say from pics and stats alone, when its just right, but at 6 days, you are certainly close, judging by how much bud is hanging - if you can - get a hygrometer and put that in the jar along with the bud. This way, you can get useful info on whats actually happening in the jar. After a couple hours in the jar, check in on things, and if it feels a bit too moise, then take em out for a couple more hours to continue drying. From the pics it does looks like you have a bit of leafy material left, and I do find that those parts give you a really good indication of how much moisture if left. If they turn limp and soft after a couple of hours, its usually a sign to get em out and dry a bit more.
