Schmarmpit, I find it interesting that your Querkle is finishing in 10 weeks. Have you been viewing the trichomes for doneness? I got my first amber trich at day 51 of flower. A few days later Im at about 6% amber trichs on tops of highest colas, and many leaves are yellowing and curling. I may allow just a day or two more. Mine has purple on the buds, and maybe a touch on sugar leaves, but not on big fan leaves. My temp range is 70-90. I describe the flowering smell to be fruity and musty. I can't say sour grapes, but more of a Pineapple/mango. I have seen that the flowering range is from 55 to 60 days. Thanks for your posts. This strain seems to be a slow vegging, low/med yeilder, but very beautiful strain with good effects.
