I recently grew a C99 from G13 Labs, can't say I saw either of those issues but I just had one example. Long, long ago I grew C99 from Brothers Grimm, 5 plants, none with the noted issues. If it is genetic I would wonder what the 'Fast' genetic was that was added, I tend to avoid 'Fast' versions as they seem less genetically stable.
For the short runty one, is it the plant closest to a fan or humidifier or something like that maybe?
I’d maybe agree if it weren’t for the 12 other plants that seem just fine - exact same medium (HP ProMix) nutrients, lights, temp, etc. They’re all in a 4‘x4’ tray together, so you’d think they’d all be stressed.
