hi buddy, the % of amber trics depends on what you want as effects( strong or light). but it advisable to begin to flush before 30% 😉….at 5/10% it s better to my point of view. There are many variables that can affect the blooming duration (pheno's traits, light used, stress technics used grow conditions etc etc) but of what I see from your photos it seems that ure pistils are still Young, same for your bud. i can't see your trics but for me your plants are not fully mature. concerning yellows leaves it could be an indication only ! This means that the senescence phase began but it can also means that you are in deficienty… and dépends on the traits of the strain some weed need to be fed a lot of others not… Definitly the best way to know when it's time to flush is checking with a microscope your trics in a range of 0 to 20% amber max 👌
