Is it Harvest time?

Definitely 100% not ready, I would leave another 2 weeks judging by the pics you posted in the question. 👍

Depend on how yo like yor weed. If you like the turn ssmoother, "clearer" you can harvest when trichomes are milky. If you want more porentcy/"couchlock" then harvest when trichomes are amber too. I personally prefer to harvest before too much trichomes turn amber, because in my opinion you just get more tired. But its personal preference I guess. If you really want to find out, harvest the same strain at different times and check how you like the result. Colour of hair is no indicator for maturity

Its too early my friend. When all the Calyx (Hairs) are brown you should check the Trichomes. I would say you have to check again in a few weeks. Probably 3 weeks. 🏻

Nowhere near it. Once a plant has 98-99% brown pistils/hairs, it is entering the harvest zone. You still have roughly 4 weeks to go by the looks of it.

To early

Not even time to scope calyxes... long white hairs tell you the calyxes have not plumped around them.. .also, most pistils should be dead by harvest (rust colored, coiled up etc). When it looks fully plump (can't discern daily change anymore), then you should start scoping trichomes. save yourself the hassle of doing it before that point.

Hey man, def NOT ready yet! Don't chop! 🛑✂️ Right now, your trichomes are still completely clear and glassy. Plus, almost all those white hairs (stigmas) are still standing straight up. If you cut her down now, you'll lose a ton of potency and yield. 📉 She easily needs another 10-14 days (maybe even 3 weeks). Wait for those white hairs to turn orange and shrivel up, and for the trichome heads to turn milky/cloudy. 🥛🔥 Patience will pay off big time here, you got this! ?🚀

Not just yet in my opinion, I'd like to see more pistils turning orange, a fuller calyx and a higher percentage of amber on the flowers themselves. Remember the leaf tricomes will turn amber way before the ones on the calyx. I'd expect a racey effect and lower yeild if you harvested now.
