Hindu Kush Auto GC Seeds

On week 17, last week I flushed with straight water 8 gallons worth. I cut off my tiger bloom at the end of week 15. Getting a lot of the normal yellowing of fan leaves. All the hairs have browned and curled back in, buds have increased in size. I got a jewelers loupe which are hard to use kneeling down. I'm observing most of the trichomes are cloudy, I'm just waiting for about 25% amber color which is hard to see. Getting close to harvest. I've read sometimes it's good to let it sit in the dark for 2 days prior to cut. Not sure how much a difference that makes.. looking like I may get about 2 oz from this.
