Landraces are many times nute sensitive and some can be big yielding, so it's prolly more about genetics and how well the plant can use nutrients.
I hope you are right, because I am doing a test grow right now and I am in unfamiliar territory with plants that barely stretch. My yield is going to be about half of what it normally would be so I am hoping for some super frosty didn't snugs in place of size. These plans are very sensitive to feeding.
