Welp, ran out of space in the tent, looks like 3x3 will only support 1 plant in these 5gal buckets. Definitely got more height this go round, so we'll call it a success. Moved the other Crit Kush outside to finish w/ it's sister that went out there a few weeks ago. Stark difference in color, though the one that came outside earlier has had a lot of weird mutant leaves so not truly surprising.
@Ogpuffz, So my last (first) grow I did LST and wasn't super happy with my results (mostly cause i'm new). This grow I decided to do as little as I felt I could get away with and see how it grew naturally, mostly to improve my understanding so I can improve my LST techniques on the next go round. The only pruning I've really done has been to take out some fan leaves mostly to try to improve air flow and spread things out to keep the humidity down.
