I thought I tracked my seeds well “perfect”, I...

Nobody can guess the answer for you, it is impossible. To me it looks more indica than sativa..........all hybrids can lean more one way than the other,

You can't desk research strains like that, genetics is just not that simple. 1. It's impossible to get homogeneous plants from any cannabis seeds available, even the most stable lines produce at least a handful of different phenotypes with very different expressions 2. Sativa/indica percentage should be totally disregarded since the whole thing is non-scientific nonsense that doesn't actually mean anything or even have a set definition 3. If you want to know something about a strain you have to find grow reports on SoMe or forums, or grow the seeds and see for yourself OG's are known to have phenotypes that stretch 200-300%. Only actual information about the different phenotypes and their growth patterns and effects are useful knowledge you can get when doing desk research. Breeders are notorious for not supplementing information because people often blindly buy whatever hyped stuff the breeders offer.

Your likely correct in the original assesment, seeds are so cross bread you can't tell from growth traits alone anymore. add onto that bad breeding practices you get some drastic pheno differences in plants. Sometimes I can smell the difference in strains, but hard to say without a foundation to compare it to. Eg. I took a bunch of clones and put them all in the same cup. it was a mix of a fruity strain and a musty skunky strain. so once they got established and had a root base, I rubbed the stalks down and smelled my fingers... and it worked lol. This would have been much much harder if they where all seed starts vs clones as they would not be identical. Grow it out and have fun with the high.

that's how you trained it to be. Needed to keep the top down a bit longer to keep it even with the rest. did you by chance strip leaves from it? the mostly look small or minimally developed. That too can cause stretch trying to seek light. and who knows. if growing other of the same strain you might be able to find enough similar traits / differing traits that you could distinguish. Which package has fewer seeds? should help out, lol. or, if you grow more in future, you'll know retroactively. Relying on what he breeder says certainly isn't 100%, either.
