How many hours of light are they under?
If 24 hours, then cut the time back to 18 hours!
Now daylight 15 hours. İ live in Turkey. Early summer. Hot climate.
....it could take up to 8-10 weeks
That's what I am finding out at the moment with my first go with seeds.
Everyone everywhere told me that preflowers/sex always appear by 6 to 7 weeks....
...but I'm coming up on 8 weeks and only 1 out of 5 so far has shown sex/preflowers, and it was a lady. The rest of the plants are not showing anything yet.
Mine were started outdoors at the beginning of May, northern-cali.
.
I recently had a plant go 6+ months not showing pre flowers (lullaby x blockhead) so I assumed that it was a female.
It wasn't.
Weird shit can happen.
People say a lot of stuff... some of it's true, but when we're dealing with cannabis there is a LOT of misinformation culled from decades of illegal growing; old wives' tales, sayings... Most untrue.....
Your plants will show sex, but only after their hormones have been triggered by the length of daylight.......
It's a learning process... this growing weed thing. Keep notes, refer to them each time you grow.
You'll get really good at it if you respect the process and focus on letting the plants thrive.
Give them a chance to reach potential.
