Tbh, i would wait at least for day 75, so another week.
If you wait untill you are at least at 5% ambers you can be sure that more clear cristals will be turning milky and overall potency will be stronger.
Got some beautifull purples there btw.
If u wanna harvest now u can do it, but your trading some serious yield for time, and you can ve sure its gonna be a head high if you harvest now, give it 1/2 weeks if u want a more mixed high, body and head, and about 3 weeks or+ if you want a full sedative high.
I'm trying to keep it short but i think i got the point across to u.
