Hey there so by the look of your photos many of your pistols still could use a little more maturing. In regards to the trichs it all depends on you preferred high. The more clear there are the more racey the high can be. Wheres as the higher number of amber will start giving a couch lock high. So typically I've heard of people seeking a 20% -40% amber with the remainder being cloudy for the balanced "perfect" high. If you're adding flushing supplements, I would say at least the last 3 days before harvest stop adding anything to your ph'd water. Black strap molasses is a good option as its all natural, it sweetens buds, and fattens too, it also doesnt require flushing the way bottled synthetic nut/supplements do. I'd say pick a bud and check trichs each day for progress, and begin flushing in about a week. Many blue dreams are finished around 10 weeks. I hope this helped in some way. The buds look nice already. Happy Harvest time. ✌️
