One of my plants is starting to develop brown trichomes. It is now a total of 50 (8 weeks) days old. According to RQS, it needs 10-12 weeks. The picture might be a bit blurry, I hope you can help me. The others are still clear.
No, at least not in these pictures. Maybe more photos would help, like from the tops and the whole plant. 9-10 weeks is more realistic, usually even 10-11 weeks. Don't ruin your harvest by getting impatient; the last 2 weeks are the most important when it comes to yield and flavor profile!
You want to look at the trichomes on the flower itself, not on the leaves. But I would say you're close to harvest. Seed banks only give estimates – and those aren't set in stone. Good luck!
