hey, a SAB sourced "pachanoi" KK2150 which was definately a orange-reddish spined cuzco variety and not a pachanoi did some strange things last year and seemed to have stalled more or less.
Two branches have done this and they are rooted separately.
I noticed this today in one of them, which was very pleasing as it seems it has started again, keeping the monster growth.
Since it was grown, cloned and sold in Australia, more people might have seen this incidence. Infact, some SAB member had the same occurence with the same plant.
