resimaxanswered grow question 9 months ago I would say that this is indeed a genetic mutation. Leaf mutations are pretty common. Breeding strains is a complicated process that takes a lot of time and effort. Quality genetics from a reputable breeder is an important aspect to consider if you value consistency. The same cannabis cultivar can exhibit many different phenotypes, or plant styles, dependent on how it was bred. For homozygous (consistent) offspring, consider switching up your breeder, perhaps with an F1 hybrid variety, some of which have very high homozygosity levels (consistent results).
That said, sometimes interesting results come out of the many different phenotypes a single strain can result in. I hope you enjoy it :)
