Hm hard story 😅 but with a short look on the picture I can tell you she isn't ready. Maybe 2 or 3 weeks more, hard to say.
But the best way to find the right harvest windows, is a look at the trichomes.
Go and buy you a jewelry micro (*40 or something like that) on alibaba, wish or co for a few euro, dollar, ... And go for the trichomes. That's the best way.
But till you have one... Just wait they need a bit more and it's worth the wait👍
Happy growing. Next time we talk about training and how to fill the room 😁 becaus the plant is super healthy and the first steps are done 👍 good work growie 🤙
