Flowering issue

[Frisbee]

Hi guyZ
Appreciate for your great comunity in advance
I grow with both Hps or MH 400 and growlight led 240 watt
And using Coco and perlite as my medium. I had great results so far.
But my latest Royal queen northen light auto doesn't inter to flowering period. She is 90 days old now. The pistols have appeared since day 45 so she have shown her sex and preflowering.
I examined 12/12 and 20/4 cycle but it doesn't make any difference. I stopped 12/12 after about 15 days. should I stick to 12/12 more?!?
I will post her pic.
I really hoping if someone could help.
Peace

No expert dude but I don't think change lights and cycle times will have helped.

In my experience day 45 is a little late to be showing sex... You sure you've not got a photoperiod seed by mistake? At 90 days I'd expect more bud formation.

Hey @Frisbee dude 90 days and no preflower? It does happen from time to time. Like @James Walker said this girl just doesnt have the auto gene.
I would just stick her on 12/12 and flower her out from there

I agree, change to 12/12 and leave it there as I am doing a photoperiod now, I changed to 12/12 and 1 of my girls didn't start forming buds until 3 1/2 weeks after switch so 15 days probably wasn't long enough last time

I stopped 12/12 after about 15 days.

If I had already done 2 weeks of 12/12 and it looked the same, I'd bail. But that's just me. Maybe you did get a photoperiod by mistake. It's difficult to give up a plant that's been growing that long. Good luck.

 

[Frisbee]

Yes I'm sure. It's Royal queen northern light auto.

Put her on 11.5 on / 12.5 off and let her ride

Thanks so much guyZ
It works and she is getting flower after around 100 days.
Let her be on the 12/12 period till the harvest?!?
or put it back to 20/4 or 18/6?!?

 

[Mr Green Fingers]

Keep her at 12/12 now mate because if she is a photo, changing it back to 18/6 will stop her flowering again and she will reveg

Having u guyZ as an advisor is a gift from the sky.
I haven't any kind of experience with photoperiods sofar. And now I believe it could be much better than autos.
I have just another issue with my cultivation.
In the summer my plants are so healthy and fine. Wether indoor or outdoor.
But when winter comes they can't grow well and they can't photosynthesis enough.(even with right temp and humidity and nuts)
My question is :
Is the lack of co2 the main problem?!?
I have co2 gens but I just want to be sure the only difference between summer and winter cultivation for indoor growing is the lack of co2...
Really appreciate for your thoughts
Peace...
