I had one that showed before she went into 12/12, and the batch after that showed five days in.

ive personally never had ta wait as long as 2 weeks. maybe close ta 2 but never more.

yes a lot of plant get pre-flower, this is flowering while its in veggetative growth.. on my bubble set up, it takes 4 days max... for soil it can yes up 3 but should within 2 weeks. really depends on the strain and your setup. if you got a plant growing fast, you can expect i fast show. slow growing plants can show fast but usually dont. on my 12/12 from seed they show their sex within the first 3 weeks of life

I vegged 3 seeds, 2 were male and 1 was female, the 2 males took 7 days to show sex, the female took 12 days. On my second grow, I had one plant, it showed female 2 days into 12/12. So, I would say anywhere from 2 to 20 days, most likely it will show in about a week.

Usually within a week depending on the strain.
