Grapefruit Auto #1 - Fastbuds Grow

Harvest time! So this girl flowered early and HARD at around day 24 or so. I started training her at day 19, but should have started at day 10 in retrospect, as her branches were rock hard by 19. I risked damaging her more than once and gave up on keeping her branches spread out after a point, and just focused on keeping her canopy relatively flat. She did multiple odd things. Her main top doubled without FIMing or topping, and she had whorled phylotaxy of her main top, but not elsewhere. The double top turned out to be a (minor) yield damaging issue, as they were sitting on a half inch, woody, split stem that wasn't far enough apart for air to get in. As I chopped away at her bulk during the harvest, when I got to this particular branch, I found a golf ball sized wad of bud rot inside this cola, where the two mains met and another cola pressed up against them. I aggressively scraped the mushy area out, taking a good bit of healthy but nearby bud as well, just to be sure that nothing bad gets into the crop. It was about an ounce and a half of wet cutting lost. RH in the grow space has been high, in the low 70's, but this was far more likely to have been caused by the horrible tightness of three very dense colas being crammed together from day 24-25 to day 69. Anyway it was a small amount of damage in the grand scale of just how dense this girl was overall. She was about the same size as plants that yielded 2 ounces from my first grow, but she managed to pack on almost five ounces in the same amount of space. I'd love to take credit for my part in her success, but at the same time, she was a really weird, dense girl all on her own I think. I'm interested in trying this strain again to see if this was a fluke or the strain is prone to this sort of behavior.
