Should I harvest my plants?

I wouldn’t judge this one by “week 9” alone. The photo shows mixed maturity: some older calyxes look well developed, while she’s still throwing fresh white pistils/new growth. That can happen with genetics or late foxtailing and doesn’t necessarily mean the whole plant is immature. The important part is to check trichomes on mature calyxes, not the sugar leaves or the newest foxtails. In this photo I can see plenty of developed trichomes, but the magnification/lighting isn’t sufficient to reliably call clear vs cloudy vs amber. If the older calyxes are predominantly cloudy with some amber, I’d consider her in the harvest window even if she keeps producing fresh pistils. If they’re still substantially clear, give her more time. Don’t wait indefinitely for every new growth tip to “finish” — with some phenotypes, you’ll be waiting forever
