The end is near my friend! (and winter is coming 😰) i would wait a week, checking daily on trichomes searching for the high you are looking for.
What i personally prefer after different tests is a 20% of amber because at this moment THC production is at its peak, while CBD levels are still low and stable, since molecules quickly become THC. Also terpene (aromatic molecules) production is also at its peak, developing gorgeously aromatic floral clusters.
Many growers harvest their cannabis plants at this moment because they prefer a more clear and cerebral psychoactive effect.
If you prefer a Couch lock weed (a strong physical sedation caused by weed) you need to wait on a high % of amber trichomes.
All this info are just suggestions to make u understand what is the harvest window but harvesting is very personal thing i would suggest you to try different harvest times and find your way for your favorite smoke and high.
Good luck Growmie!💪
