Difference in plants

I agree with most responses, that it is likely that each seed chooses its own potential. I’d also consider that some gals may have gotten different lighting in the middle or edge or that some were taller and therefore receiving better light than the shorter ladies. I’ve seen people mixing huge jugs of nutes and they can’t possibly be accurately and equally distributed that way. I think there must be some variation between the top and bottom of the mix and that would certainly cause a variation in growth.

Genitals I mean ... genetics

High Dan, Why do all the human brothers and sisters not look the same? Every seed has some genetics from the father and from the mother plant. This amount of father and/or mother plants is different in every seed. If you want plants that are all genetically identical to eachoter you need to use clones. These are not brother of sisters but they are all the same plant with exactly the same genetics as the mother plant where you cut them from. You do have a nice indoor jungle Mr. Weed Man! Happy Growing! 😋

They aren't clones, so you have genetic divesity. Even so, you'll likely see some differences due to environment. they 'can' make them more consistent in outcome, but that consistency also partially correlates to less vigorous growth due to inbreeding that is going on. Some do this well and retain great vigorosity and consistency in physical traits, and others do not. I had some F1 green poisons that would usually show more variety and they were all very consistent, surprisingly. Can't expect that, though. read up on this plant and you'll find inbreeding just 1 generation can have drastic impacts on rate of gowth.. not always but is a risk. (google genetic depression, dioescious, outcrossing etc for the vocab.. lots of sites to choose from). dioescious plants (m/f genders / outcrossing reproduction) can have severe negative impacts from just 1 generation of inbreeding. Also, your pots have slightly different things in them... your lights provide different amount across canopy.. there are smaller environmental factos at play too. some may be sensitive to the feed given even though the others are sister plants sharing some but not all of the same DNA. It's pretty tough to be 100% consistent for all plants... mainly the light intensity differences.. can circulate air well enough to mix temps and RH to equilibrium easily enough. if soilless or hydro, easier to maintain consitency in root zone etc.. always something different even if tightly controlled as in a lab expirement. none of this is guaranateed.. it's all pobability... of vaious likelihoods. there are non-inbreeding methods involving multiple independent lines that share wanted traits... this takes a lot more effort, resources and time.

Genetics for sure, but the leaf shapes aren't too far off. I see 2 maybe 3 different plants out of 8. I think it has to do with your environment too. Look where you humidifier is, no way the VPD is the same at the back of the tent/room. Plus 1 or two have some interveinal chlorosis, so deficiencies and excesses will cause the plant to grow differently. Good luck on finishing out your grow.

The short answer: genetics. Each variety(strain) has what is called phenotypes. After a cannabis plant gets pollinated, the DNA from the parents are shuffled up and redistribute dominant and recessive traits. These genetic traits are what determine how a cannabis plant grows, handles pests and mildew/mold, THC content, terpene and trichome production, color, etc. I hope this helps.

That's kind of like expecting you and all your brothers and sisters should look identical. Unless all clones, plants will grow differently from seed in same strains.
