CFL 10th week of flowering question

So the plants are on week 10 of flowering in a CFL growbox. I checked one of the strains (all strains have 8-10 week flowering time, although I am aware it can be longer for CFL) and under a microscope the trichomes are about 90% cloudy 10% clear. I want them to be 10-20% amber the rest cloudy. Roughly how long should this take??

Running: 200 watts of cfls in a growbox, big bloom nutes w/ bio grow. flushing now. On week 10 starting today.

give it another week mate at least
