I've been flushing the past few days before inducing flowering, which I'll be doing this week. The plants have been filling out very nicely the past 2 weeks. No males (knock on wood).
@CanadianFillmore, thanks. It's the one plant in the corner which is/was growing heads and tails above the others. Got feminized seeds from second-hand vendor, so I'm curious myself. Most are 3-4 feet, except for the 3 5+ footers
