Looking for advice on time left to start a flush?

Depends on the type of high you want. Regardless of terpenes and genetics if you harvest with milky thrichomes its the peak of the effects you get sedative and active high. If you wanted fully active high, well, its about time when the cristals are milky, as when you get cloudy/clear/amber all at the same time being the majority of them cloudy, you get the widest spectrum of effects. If you want it basically fully sedative, just hold on for a couple weeks untill its fully amber crystals and you got it. Its up to you. I like to harvest them at a point where some might say its a premature harvest, but i know what i'm aiming for, it just blast my mind everytime, since i need to be active and can't even risk couchlock i harvest with clear crystals. I get less yield but i get the high i want, and its better to get 70% of what you like than 100% of what you don't really want. Stay well, and good growing growmie. P.s. in future questions use a picture of the thc cristals, not the pistils, as the pistils are useless to determine when is the crystal really done. Pp.s. if you dont mind pick my answer as it does help out a lot in the grow questions contest.
