Do these look almost ready to dark cycle?

Hey there good looking plant. I would say just by the photos you can’t see the tricombs you have to get a jewelry scope to see the balls on the end of the tricombs good enough to see the color. Although in the photo the buds do look fully developed and pretty much all the hairs in the photos have changed. I would suggest if more than 80 to90% of the hairs have changed color on the entire plant then I’d say your good to harvest Also you don’t have to be perfect on timing with harvest no matter what the buds will still get you high I have chopped down plants super early b4 with like 40% the hairs changed and 0 amber tricombs and the buds still got me high Good luck
