i've never had plants ready to flower in just 3 weeks from seed.

if you don't have alternating nodes, it's not sexually mature and
so, not mature enough to flower.

i'm no expert though, maybe we can get Stinky to share her knowledge,
or one of the other experts.

Like others said, they should be showing any day now. Some strains just take longer than others.

As for the question of when to flip the lights, it seems to be mostly a matter of preference. Some like to wait until the plant is showing sex on it's own, or until they see alternating nodes. Other's (like me) make the decission based on size. If you're growing something like White Widow that tends to get rather large if left to it's own devices, then you should flip the lights when the plant's about 1/3 of the finished size you want. Even if they're not quite ready to flower they'll still start in on their pre-flower growth spurt.

FWIW there are some growers that run 12/12 from day 1. As far as I can tell there's not really any ill effects, which makes me wonder if it really matters that much lol.

i've also heard of people flower from seed to show the sex quicker and when they find the young ladies,,they stick 'em back into veg.
lets hope i get more ladies,,but i think i have found a boy too,,not sure yet though.

Sounds like they weren't feminized seeds. LOL 4 is twice what I have so to me you're lookin pretty good :thumbsup: But seriously, try 24-36hrs of darkness before you go 12/12. My small plant showed female 3 days into flower and the big female showed at 9 days. It's suppose to help them ease into flowering at a young age. I'm so happy theres an easy cloning system(DWC) so I don't have to worry about males. It's going to make things almost too easy

i,ve ended up with 5 females out of 9 feminized,,but i wont complain cos they were only £10 for 20 seeds and as i bought 3 packs of them,,i got another 20 for free.
