Congrats on bringing your plant up to this stage! 👠When to harvest can be a matter of personal preference, provided you are within the harvest window described and illustrated in GWE. You're there, so it depends now upon if you're looking for a more stimulating, energetic high (cutting earlier when pistols still have some white and trichomes haven't gone amber), or waiting for the amber trichomes (when a more relaxing, even sedating effect occurs due to some THC degrading to CBN). Now these are generalizations, so there are variables which can still influence your potency and individual experience. Personally, like to harvest on the early side, for more of the stimulating effects. Enjoy the well earned bounty! ðŸ¸
