They seems very small. Dont u want them fatter?
She got nice set of a healthy leaves and I believe she can made bigger buds.
Trichomes I think are mostly milky, no seeing any amber.
If leaves which tip are getting dry are the oldest ones, than thats not seem to be a problem.
I would wait 1-2 weeks before harvest, but u can chop her now if u want.
I always flush every plant before harvesting, sometimes thats what buds need to get some mass.
