Yeah....the truth is that you may have just gotten a dud. It happens.
You may have gotten a seed that expressed all the poorest traits related to the cross. That's one risk when you grow from seeds made from complex hybrids. Too bad there aren't more "landrace" seeds available. I say that in quotes because a landrace stops being a landrace when it's not grown in it's native environment....but you get the idea.
Diverse breeding works great for humans. We don't want to interbreed with our own brothers and sisters, obviously. But, for cannabis plants, the closer-in the genetic line stays, the better.
One big reason we get plants with very little smell, has to do with the plant selections going on dating back to the 70's and 80's. Growers back then didn't want the stinky strains that we all love (and miss) today. They bred for low-stink and high THC content. And that's the way it stayed for decades. Now, we are suffering the backlash of that selective breeding.
