Looks like it's been treated with Paclobutrazol. I would stay away at all cost! It's carcinogenic and the only permitted use is on ornamental plants.
It forces the plant to be dominant in producing carbohydrates in its tissues instead of cannabinoids. There's good and bad PGR's, the main problem is people use them incorrectly.
Monosaccharides and their chains has larger molecular mass compared to cannabinoids. It adds bulk and decrease quality and make it carcinogenic.
