2-3 weeks more.
they aren't plump yet. lots of long white pistils. when the calyxes plump, the pistils 'look' short. At that point, start scoping trichomes.
ignore whatever the brouchure/web site said about flower time... simply observe and react. After you put in 70-100 days, stay patient at the end too.
Don't defoliate them like that and you'll have better results, too. You stripped a lot of leaves too late into flower, because i only see small fan leaves. What leaves remained never had a chance to grow out well.
