Hey,
That image is pretty accurate, you can guide yourself but that.
As for how long it takes, any where from 5-14 days... really depends on a couple of factors.
It's definitely worth the wait, you'll have richer smelling and tasting buds. Also a bit more weight and density.
When you start seeing cloudy trichomes, if used nutrients then you'll need to start flushing those last two weeks.
She's looking great!
Good luck and Happy Growing!ππ±πΏπ²
