First off, the buds are nowhere close to ready. A pic or two of the entire plant and couple individual buds would help folks give u better advice.
also, it’s been my experience with autos, that some never really get amber trichs.
Make sure the buds are ready and fully ripe…..let all white pistils turn brown and recede. A random white pistil popping here or there is no big deal, but if the plant has them all over, it’s not ready.
The one mistake I’ve made numerous times, is waiting and waiting on amber trichs. At a certain point your terp profile will start to decrease and your quality will suffer.
All of this is totally dependent on the plant being healthy and in good shape at the time.
Plants that are sick , deficient , toxic, underfed, overfed, PH out of whack, etc, will not finish up like they’re supposed to.
Pay zero attention to the breeder’s timeline….thr plant will finish when it finishes……but don’t lose terps by waiting on something that may never come.
