Genetic degeneration? Single-edged leaves

Hello everyone, friends. I recently received this OG Kush seed that is showing this single-pointed foliage. I would like those with more experience to tell me a little about this type of anomaly, how much it affects the final result and whether it is worth keeping or crossing something like this. I thank you in advance.

Any chance of a reveg happening?

@Foreigner Apparently not. It is being maintained at 12 x 12 hours and the flowering continues to progress, albeit slowly.

Your first and third pictures look normal enough but the middle one seems a bit off.

That said it’s not totally unusual to get singles. I find that the numbers go up then down over the course of their lives.

Best of luck.

It happens when the auxins get messed up, like when topping/super-cropping in flower. There could be other reasons too, like genetics.

Interesting @resimax .

I didn’t know this information.

I use topping/super-cropping techniques during vegetative growth on almost all my plants, but it had never happened like this before.

That’s when I started to suspect something related to genetics.

Thanks, friend.

True og kush is actually known to do this. Or at least a lot of people have put that in writing on the interwebs.

As for genetic degradation, people use to call it genetic drift. It turns that genetic drift is actually the proper name for genetics changing gradually over multiple generations of open pollination in large populations since no one offspring will ever be a perfect genetic copy of either of it’s parents.

What we used to call genetic drift was likely epigenetic stresses compounded over time and/or undiagnosed pathogens.

I have heard this many times with the OG kush varieties and its a stress response, chemical ferts?

Could be rootbound too. when the plant’s roots aren’t doing well it can’t support a ton of big leaves so sends a message to make leaves as small as possible.

Conversely, when the plant is happy, it gets big and throws many bladed fans

It has to do with auxins, its not necessary bad, you are just pushing the system, and not all organic is organic anymore smh lol anyways its auxin related that much is sure

I don’t run exactly 12/12. Usually 11.5 on and 12.5 off. Manual timers can be off by 15 minutes both ways. Your plants look fine to me. I’ll have them do that sometime. Even just 3 leaves instead of 5 or 7.

@SchmoeJoeRising If it’s a clone that people feel has changed phenotypic plasticity is often to blame, disease is another culprit.
People talk like epigenetic changes are permanent when in fact they are not. If it’s a seedline that is degrading over time inbreeding depression is often something to consider along with poor selection.
To the original poster , I’ve seen many plants that throw singles like that that , it wouldn’t even realy stand out as odd , what I do notice is that plant has thin leaves and stacks much different then og kush. Looks more like the platinum og that used to go around.
Og kush has fat leaves on a spaced out frame with golf ball sized nugs

I’ve also heard the same about triangle kush but I don’t have much experience with either. As for phenotypical plasticity, I looked it up, but the only information I could find on a plant losing it was referring to multiple generations of sexual reproduction.

The only connection I could find between it and clones was the influence that a mother plants phenotypical plasticity has on the development of the clones taken from it. I couldn’t find anything about clones losing it, though. Do you have any info on it you could link me to?

Phenotypic plasticity is a reference to epigenetic changes causing different gene expressions to express or not. It’s not something they lose but rather something they do based on a variety of factors.
A lot of the (this is not the same plant it used to be )conversations are caused by this but alot are also caused by s1s passed of as the original or dudded plants. Some strains are more sensitive to changes in there environment then others.

Do you know of any proven methods to reverse negative epigenetic changes? I’ve read up on meristem tissue culture being effective but haven’t seen anything else.
