When can I Harvest

She has a while to go at least a month. A great way to tell when she is ready. In a few weeks take keep your eye on her color. She will seem bright and shiny. When she is ready it's almost like she turns her lights out. She will be darker and dull. Clear tricombs seem to make them shine and look bright. When they're all milky the shine is gone and she will look dull.

3-4 weeks or until there are at least 95% brown pistils.

Okay so 2 weeks after the mass majority of pistils turn brown on the plant is easiest way to get close without inspection of trichromes under a jeweler's loupe.

At least 4 weeks is my opinion. That’s assuming you end up with a faster flowerer

You've got a lot of time left... she hasn't even started her fade and she's got a lot of fattening up to do. It would be helpful if you had a diary for this grow - and if you could get a zoomed-in photo of the trichs... but you don't even need that now as the pistils are still all white. Start looking much closer at the trichs when the pistils get 50-75% brown... I'd say at least 4 more weeks... Good luck
