Its all on what kind of high you want look at heads of the trics. The mature in the order of Clear = low thc Cloudy = highest thc Amber = degrading thc ***You can also get amber trics from damage. Assuming you are doing a 1 week flush. If you want a more head/energetic high then you want to start flushing when you see 80%-85% cloudy and 10-15% clear and 0-5% amber If you want a more body/couch lock high then you want to start flushing when you see 80%-85% cloudy and 0-5% clear and 10-15% amber As NobodysBuds says check the calyx( teardrop that the white/red hairs come out of) Also if your canopy is not even then the top buds will mature faster.
