Almost done? What do you guys think? How much longer should I let them go?

Oh how beautyful they are! You already got some amber going on but most of them are milky so it's more a decision based on the strain and your personal preference. If it's a mostly sativa strain is preferred to harvest with fewer amber tricomes. In case it's a indica strain you can wait a bit longer until you can really see some gold going before harvesting for higher CBD. The same applies to personal preference. IMO I would wait a week but checking every day as some strains can really go from mostly milky to mostly amber pretty quick and you don't wanna to have a golden nugget on your hands. Congrats for that wonder plant.

I would drop all nitrogen for a few days then give her a flush for maybe 2 weeks and then you will have yourself an amazing smoke. Enjoy mate you done real well there.

Looks like 10-14 days to go. I would start flushing.

Looking good 👍, i think even 1 week more and ready
