Hey mate !
I personally harvest when the tricomes are 90% cloudy and 10% clear/amber, in this stage the plant are in is full potential of cannabinoids!
Keep in mind that, more % of amber tricomes more sedative will be the high! So if you aim that high let them ripe more till have like 60% amber or so! It’s fun because you can test harvest in different stages of the tricomes and see the difference!
Wish it helps mate !
