The RQS CBD mix have popped up nicely, with PainkillerXL being first out - and I really want this one to do well! Unfortunately, Royal Medic didn't germinate... It took over a week for them all to germinate, and a bit longer past that to push out, so I am thinking that the temperature was a bit too low still - it has been almost freezing at night..! There's no issue with seed shells being stuck or ripping leaves or stems. The propagation light was a Favrison Castnoo 54LED, that was advertised as being as good as a 300w HPS, but it was really more like 3w :d I tried using two, but that didn't help - they are no good at all, really - may as well use the window ledge! That's gone in the trash..! So, this guy is going under the MarsHydro TS-1000, which is a 150w LED and is a great quality light, imo :) There are a few autos under the same light, but there is plenty of space for this guy at this stage.

Grow Questions

This plant has developed whorled phyllotaxy on only one side of the initial manifold divide. The other side is regular, opposite. I'm curious as to what may be the reason as to why this happened only on the "dominant" (faster growing) side of the split? 2nd one this season...

I think what you might be seeing is simply a genetic mutation... not common but certainly not unheard of! Good luck!

have you smoked this strain yet? Wondering how it tastes and how potent it is

@XperencdGmanXG, Hey bud! nope, not tried it, but I'm having a time trying to keep it inside a small footprint! It's starting to really want to grow straight outwards! Give it another several months and I'll be able to tell you :P I don't think it can be much more than 12% THC (at least I hope not), but that's pretty strong for a CBD strain!

The answer is: Mutations in the R2R3-MYB117 transcription factor elicit trifoliate leaves and initiate axillary meristems... The trifoliate mutation is caused by a truncated MYB117 transcription factor that alters cellular homeostasis and fortifies γ-aminobutyric acid, folate, and carotenoids. That's some fancy big wards you gots thar mistah! So, basically - the plant is a mutant!!! If the plant wasn't put under such stress as being topped like this, then this mutation most likely would have never shown itself..! The mutation was expressing along the STEM/MAIN of the plant - the other stem/main was a BRANCH until it was forced to be a main. The mutation forced the cells along that line to go a little hinky due to some chemical irregularities - but I think that surgical intervention has done the job and corrected the growth pattern. Since all branches have assumed "main" status, the whorl has resolved to opposite :D It's also true that the hormonal chaos that follows such a shift in growth as this This correction is likely a result of the same mutilation as the thing that caused the issue in the first place! The apical bud being snipped off, and its non-mutant expression branches becoming the new apical mains..! In addition to this, I believe that I also by chance have cut off the apical bud that carried this expression at the second split, and the new mains are from both branches. Fingers crossed it doesn't appear again. It is therefore not able to continue to express the mutation along that main, as it no longer exists and the whole thing has undergone a hormonal rewiring to grow in a very unexpected way! It's a recessive mutation - as trifoliate phenotypes are segregated independently as monogenic recessive mutations. The mutation is still there, but it is being hidden by a more dominant gene expression (ie, "normal")! This is useful information! RQS' entire line could be hiding this mutation, and they'd not know it until every plant was carrying it! Interestingly enough, the mutation appears to be more prevalent in non-phototropic plants (autotrophs!) than phototropic plants! (additionally, gene MYB117 appears to have some bearing on flowering time: https://pubmed.ncbi.nlm.nih.gov/33779489/ ) It would be interesting to find out just how many of RQS' plants in this strain have this characteristic, and if it is similarly expressed or able to be reproduced through sharp force trauma to the main stem!

I don't accept "coincidence" or "curious occourance" as a valid answer..! The potency is not in question! What is, is how and why one side is trifoliate, but not the other, when it would be expected that both sides might be..?

Looking back, I can see that there was some massive asymmetry going on with this guy... "the bat", because it was so lop-sided... I've one in the ground outside that is also whorled, but this isn't so much of an issue as it is growing untrained. Reading up on the mutation - it does say that most of these turn out to be male. This is a shame, as I was very much looking forward to Painkiller XL, however - there are worse plants to have as a male to pollinate the others, huh? Shame it has the trifoliate going on, or it'd be a good candidate. // This isn't a clone..!
