Should I harvest?

You should look at the trichomes with a magnifying glass, and when you have 2/3 milky trichomes and 1/3 amber, then you can harvest. But 2/3 of the trichomes should be milky. Yours still look about 80% glassy if I'm seeing it right. The pictures aren't great for assessing.

Hi 🏻‍♂️ Cannabis is usually harvested when the trichomes (the tiny resin glands that look like crystals) reach the right level of maturity. Clear trichomes mean it’s too early –the plant isn’t fully potent yet. Milky/cloudy trichomes mean the THC is at its peak, giving a strong, energetic high. Amber trichomes mean THC is degrading into CBN, which produces a heavier, more sedative effect. 👉 In the photo, most trichomes still look clear to cloudy. That suggests the plant is not quite ready yet, and you should wait until the majority turn milky, with around 10–30% turning amber, depending on the desired effect. Hope I can help.

She still has a while to go. Lots of fresh white pistils indicate she is still growing. That branch with all the dead leaves looks worrying though. You either have bud rot or fusarium in the stem of that branch. If it is either one of those, cut it carefully and dispose. Hopefully the rest of the plant isn't affected.
