To be honest people should really explain to first time growers that they should really look at the buds to determine if they are ready to chop.
You still have maybe 2-3 weeks. Trust me your plant is a beautiful, just do her justice and let her go a little more.
Do yourself a favor and really look at pictures of buds ready for harvest. Going by trichs can be misleading because sometime amber can show when the bud still has like a small % left to finish. Experienced growers will tell ya that the buds swell up the most at the last weeks of its life cycle.
