Yes looking ok full steam ahead, those calyx are still all pure white, depending on whether you counted flowering from the "Light schedule change" or "First sign of flowers", it can take up to 2 weeks to even show the first flowers after schedule change to 12 hours of dark. I say your more inbetween week 4-5 somewhere, personally, I always try to defoliate in small doses every couple of days from 2 weeks prior to the stretch all the way until the stretch is over and no new fan leaves will grow, leaving only the top 4 most exposed internodes, buds look great but could use some defoliation to open the canopy.
