Another variable could be how I watered this time. I built a drip feed system to feed the same amount to each plant, and turns out that wasnt a great idea, cause obviously they will need different amounts of water, they're from seed not clones. So, if a plant didnt need water that day, i'd redirect the dripper to another, more thirsty plant, that way I'd avoid overwatering. However, I dont think I'd do this again unless I was in bigger pots, or if I was doing it all from clone where everything would be feeding roughly the same. I also had probably 2x the amount of plants I'd stuffed in here before since I was doing 1 gallon bags, which probably did boost my humidity to unstable points where there was lacking air circulation.
Either way, everything is now chopped, tent is empty, being cleaned out and reset so we can avoid these problems while we upgrade to bigger and better things.
