I hit 2.6, my best run so far, very happy. I trim everything by hand, tried many machines and techniques, hang dry 60rh/60F for 5-10 days, jacks 321 with silica, 1200 ppm all the way thru (strain dependant), 1500 ppm co2. I feed 3x a day in coco. Did a lot of testing and this seems like the best...
