@Calyxo, I wouldn't flush until I start setting nearly all cloudy and a few Ambers. Then you have 7-14 days for them to turn abit more amber and fully Mature, they will fatten up at this stage quite a bit! Or it could be that your light is too far away or just not powerful enough. Removing a few fan leaves will help get light further down.

@Fruitgrower, should I do another light feeding before I flush? Trichomes I'd say are about 50% cloudy and some fan leaves are starting to yellow and wilt... How will defoliation help at this point if you don't mind me asking? Also I'm past 9 weeks into flower,, shouldn't they have bulked up by now judging by the other signs already pointing toward the end of flowering

Don't rush the flush mate. They look like they still have some bulking up to do, try a small defoliation perhaps?
