Harvest time, waiting game?

Hello Your grow is looking great, I'm seeing a fair amount of amber trichromes in your photos so I'd say the harvest window is opening. Some of your leaves are getting some fade to them, i think because your plant is almost entirely big main colas without having those larger fan leaves seeing a nice fade isn't as obvious. with top dressing dry amendments it's a little harder to tell when the nutrients have been used up. I think you're doing good to keep up the plain ph water and probably will be ready to chop here within a week. Happy harvesting.
