Question about sexing

Do I have to change the lights to the 12/12 cycle for the plant to show signs of what sex it is? It is approx. 2 months old. Maybe I haven't waited long enough...

Yes, you need to set your lights on 12/12 cycle for the plants to begin flowering and show their sex.

No you can sex your plats at 14 on 10 off and flower at 12/12. If you wanna sex them just put them on 12/12 for 1 day then back to regular light cycle and in about a week they''l show sex

So, I should add the 2700k lights now too, huh?

you don't have to change your lights. you can just go 12/12 and wait. its all a waiting game at this point. Someone said waiting is the hardest part..well they must have grown green.

Ya 2700's for flowering.It's working great for mine

i used 12/12 to find my sex but while doin so i had some in veg still that sexed before the 12/12 sexed...it all depends some strains are autoflower and will flower in veg still...i dont recommend the 12/12 then back to veg...if you start 12/12 jus do 12/12 the rest of the way...as far as the 2700k you should add for flower but a wider spectrum is better like 4 2700k 2 6500k somethin like that
