A strain that is marketed as 8-10 weeks is likely going to take the home gardener 10-12 weeks, (or more) depending on your equipment, soil or hydro, experience level, nutrients and climate. (indoors or outdoors)

A mature plant will have predominately milky or cloudy trichomes. An over-mature plant will start showing rusty or amber trichomes. Waiting for the rusty trichomes can add extra weeks to the totals.

If I was going to keep waiting, I'd offer half-strength nutes, once or twice. But remember...you will still have to dry and cure her, which can take from a few days to a few weeks. Don't over-do it with the nutes. Also, keep in mind...you have no fan leaves left, so any guesses where the excess will go?

Would also back off of the molasss if you're going to be adding the nutes. Molasses is like a 'nutrient kicker' that amplifies the nutrients effects. (a slight oversimplification, but accurate)
