sexing question

[pufpufgiv]

These plants have been above ground for 30 days and show no signs of sexing. they are under 4- 20 watt flouros. They have been on a 24/0 light schedule since germ and was just switch to 20/4 for 3 days now. may go to 18/6 here shortly. Since my mother/clone box isnt very big I have been LST'ing them for a couple weeks now. I just FIM 2 days ago and have trans planted them twice.
Could the added stress be causing them not to show sex or is it common to go 30 or more days without showing sex. or am I doing something wrong? any and all help is appreciated, this is my first indoor grow in a cab. Here are some pics.

If you want to get them to show sex you need to drop the lighting down to 12/12. At the light you are giving them they will just continue to veg......

thanks JJ....I am trying to get one good mother out of these 3. so correct me if i'm wrong.

I put them into 12/12 until they show sex and then once sexed put them back into veg lighting if i dont want to flower them...correct?

thx for your help

You have it correct puf. After they go back into vegging again you are going to want to take a couple clones off each plant and mark them to the mother they go with. Then when you flower them you will know which plant is best to keep.....

Looks like the educator has got you covered bro.

Good luck.

I veg all of my plants for 6 weeks, 18/6 and 95 percent of them show sex before going 12/12.
Drop the hours like said above.

Good luck with your project. The strain I am growing now showed sex on the third day under 12/12. So it wont take long if you keep a sharp eye out. Two white hairs is all you need. I use same trick as greenisgold on grow times, cant go wrong.

Even if you run them on a vegetating light cycle, they will eventually show preflowers, and the males generally do before the females (but not always). There's no saying really how long it will take, it depends on many factors, such as genetics, light output, stress etc.
You use a total of 80w of light, which does not allow them to grow and evolve at will. They're pretty small for 30 days of vegging, I must tell you that. Surely their rudimentary development ties in with the absence of sexual maturity, but it's not unusual with genetics that go 30 days or more before entering the prefloral stage.
Take them down to 18/6 and give them another two weeks of vegging (if your space can take it, that is).

Another pretty quick way that doesnt require the prospective mother to ever be put under a 12/12 photoperiod is this.Just take a cutting and put it under a 14 dark 10 light photoperiod and it'll show sex faster than the normal 12/12.A cutting doesnt need to root to show sex.
