I’m not sure the genetics on that if it’s more sativa or indica. But I would wager you have at the very least 2 weeks, probably more like 3-3.5.
These plants are still in the putting on weight/stacking buds phase.. aggressive bud growth basically.. then it will slow down and taper off and your stigmas/pistils will begin to “die” and turn brown.. that is around the time when you want to harvest.
Take your time, don’t rush it cuz it will be inferior if you chop to early cuz you couldn’t be patient! Trust me i know it’s hard sometimes but you’ll be rewarded. Good luck!
