No flowering with 3 month old plants

Hi there experts,

We have got a customer who has an issue with his plants not flowering.

Below is his information:
I got super lemon haze autos and they are now 82 days old with no flowering. I thought they were about to with the look of the those hairs but nope. Just growing and growing.

Those 2 have covered a 4x8 screen. (I scrog). I’ve always put them on a 12/12 light cycle. Been on that for over 3 weeks now. Temp stays 82-78. And before you ask there is no way for any light to get in when the lights go out. Absolutely no way.

Besides air, which comes through a tunnel, nothing can get into the room!
What is the deal? What can I do? Please help.


You could try 48 hours of darkness then switch to 13/11 I have never had this happen to me let me tag in some others @Hellraiser @Nicky @MidwestGuy


I’d ordinarily suggest going 12/12 with a stubborn auto, but the OP has already done that. An extended dark period like @dirtydave suggested is the next step I would take too.

I would also look for any spurious light source that could be keeping them in veg. Even though they’re autos.


My first thought would also be that there is a light leak.

Are you 100% positive your timer is still timing off when set?


If they are autos, then you have an alternate light source keeping them in veg. What was your initial light schedule before you switched them to 12/12?

You say it has hairs? If so then it’s flowering. Pics please

U got hairs on them buds like white hairs?

On the top right u’ll see ur profile pic. Next to is 3 lines click them. Then like 2 inches down the page on the right side should be the new topic. Just above everyone threads. Good luck. Seems like a major nute issue or pH problem. One thing I see is u say u pH at 6. Something all coco calls for 5.8ph on. Try to get the pH in check and watch her fly away.

Honestly I have no clue on what the Bergman bags even look like lol. I know 0 about Bergman nutes and soils @MidwestGuy @AfgVet @MattyBear @Covertgrower may be able to help on this but I’m clueless on these Utes. I use all my additives with jacks

Sorry, I don’t have any experience with the nutes. I’ve seen a few people using them but can’t remember who off the top of my head

I don’t use them either. Jacks for me too. Haven’t had enough coffee to remember who has :man_shrugging::thinking:


Me either, and I can’t think of anyone. No coffee yet for me.


Could be too many nutrients or your ph at the root level is off. The others look good, so I’m not sure what happened with that one


Have you taken any runoff numbers from the problem child? That will help tell the story
