delayed flowering / does not change

The seed may not have the Auto gene, so you may have to switch light schedule to 12/12.

*small typo - gave BioBloom, not BioGrow* Hi bud. 9 weeks of veg for an autoflower is not the norm, but it can happen. My Granddaddy Purple auto took about 9 weeks as well before the first pre flower appeared and her lighting was 12/12 from the start. Mind you, it may have taken longer had I not given her a small shot of BioBloom(n+P+K) three days beforehand 😇 In your case, you could switch the light to 12/12 for a week and see if that helps. You may need to keep it at 12/12 throughout bloom though if that is what she was needed to flip. Hope this helps, even just a little.

You can try going to 12/12. It might help and it might not. I've seen autos that never fully flip too, even under 12 hour light. Due to their nature, autoflowering seeds can have a wide genetic variation and in my opinion a higher rate of negative traits and mutations. I've seen whole batches of seed do this. Don't blame yourself for this one, it's on the breeder.

Hi, I saw that your Black autolemon is an F4 Crossing. For Autoflower plants in the fourth generation (F4), there are some specific aspects to consider. Genetic Stability: Even though F4 plants are more stable than earlier generations, there can still be genetic variations that affect their flowering behavior. Autoflower Traits: Autoflower plants typically bloom regardless of the light cycle. If an Autoflower plant isn't blooming, it might be due to genetic instability or simply eliminated due to a genetic error. maybe environmental factors. Environmental Conditions: As mentioned earlier, temperature, light, and nutrients play a significant role. Even slight fluctuations can impact the flowering cycle. You can try switched light to 12/12 if you have the possibility

I;ve seen some autos veg out forever 7 weeks or more and then slowly flip. Its not ideal, at that point might as well grown a photoperiod and gave it some HST. The thought is autos won't have enough time to recover from the HST and here this fucker is 9 weeks in lol. I am seeing some signs of sexual maturity on the plant like pistils at the nodes but not anything about flowering. I think the advice from the others in on point. Might as well flip em to 12/12 and see if it helps. will know if about a week or twos time if it is, As long as DLI is a bout the same 18/6 or 12/12 will give it the same energy to grow. With my lights 40% at 16/8 is the same as 60% at 11/13.... I don't use traditional 12/12 and 18/6 as my lights are overpowered at the moment so I need to use less to hit the target. Good Luck!

if not on 18/6 cycle, adjust proportionally... 12h is 2/3rds of 18h, so you need 150% (or 3/2nds) power to provide equivalent DLI. 16 to 12 would be 133% more power. easy peasy math.

after 9 weeks time to believe it was a mis-packaged photoperiod or the breeder cut a corner with the autoflower process and got a ratio of photoperiods etc... i.e. human error on the breeder's end. i'm not sure if the mutlip step process to get autos is 100% or if it's some greater than 99% probability. Maybe it's unlucky, but more likely human error. if your light is powerful enough, bump up power 150%, same distance and reduce light from 18 to 12 hours/day. This will provide the same DLI to your autoflowers and yield will not suffer one bit. Hopefully you got some headroom on light power. Or, if you have a second tent and light, put it on 12/12 and remove this plant from the 18/6 auto tent.

each seed is different and you could have gotten a random one that wasnt all the way stabilized and it has the fast flowering trait rather than full autoflower trait. tbh it looks like it may be about to start flowering based on the picture of the top main of the plant in the first picture. Give it a week or you could reduce the light schedule just to induce flowering. it may even react without needing to go full 12/12. ive ran autos with 12/12 for flowering cycle and it didnt affect yield in my experience. ill check out the full diary and send you a message if i see anything else that stands out to me.

Yep I agree with Eggie420. I had a critical cheese auto that perpetually vegged for ten weeks until I flipped the light schedule to 12/12. Then she started flowering. It’s possible that the seed isn’t an auto and was miss classified. Flip the lights to 12/12 and she should start doing something. Best of luck man.

Hello Kinyiraz, That doesn’t sound normal. I’m not the biggest expert on autoflowers, but if your plant is at week 9 and still hasn’t started flowering, that’s definitely unusual. Are you sure it’s an autoflowering strain? There’s always a small chance that the seed bank made a mistake and gave you the wrong seeds. If possible, I’d recommend switching to a 12/12 light cycle to see if that triggers flowering. Your plants look healthy, so this might be the best way to get them to flower. Best regards, and happy growing
