Funny Nepal Jam Fem

[Woodsman11]

I am growing a Nepal Jam indoors under Led
lighting, with lights on for 12 hours, and off for 12 hours. It has been growing since 1/30/24 making it about 12 weeks since it sprouted.
Now what I don't understand is why it is flowering already? It is growing great, and has huge fan leaves, but why flower with no change in photoperiod, and the fact it's only 12 weeks old?

12 hours, and off for 12 hours.

That's the timing to flower the plant.

If you want it not to flower you need to have the light hours more than 12, like 14.

At three months old the plant is sexually mature so will flower if the hours are 12:12

Get some pics up if possible

Welcome to the forum btw

Welcome @Woodsman11 thanks for your support!

As @exoticrobotic correctly pointed out, you need to provide for growth stage a longer photoperiod (typically 18 hours of light per day), then switch to 12/12 to start flowering stage.

If you started Nepal Jam from seed at 12/12 photoperiod, she will start to flower after reach sexual maturity, approx 2 months of life in case of Nepal Jam.

I had a Nepal Jam fem begin flowering under 24 hour light, it ended up being a stunted stunner. It had the beginnings of a main cola at 35 days from sprouting.

Thanks exoticrobotic, Dubi, and 5alamander, for your input on the Nepal Jam.
This is only my second grow of regular feminised plants, with the other grown during summer. Been growing Auto flowers mostly, so your help is appreciated!

Did it happen when the plant was rootbound ? Nepal Jam early flowering phenos, especially males, may semi-autoflower indoors when rootbound and under low light intensity.

Possibly carrying some stress from before transplant, but it was in a 2 gallon pot and probably only grew 35cm tall by the end of flower. I would love to find another like it!
