Interesting, I also have three of these at 8 weeks one is heavily purple and crusty, one only has flecks of purple but even bigger buds that are taking longer to develop, and a very strange plant that is taller than the other two with mutated leaves that are dry and leathery and shrivelled, but still producing a more bluish purple and surprisingly decent looking bud.
@EazyRider, yes there are 3 different phenotypes at least , but I’ve always wondered if you just grew one which one would it be and if you grow three do they communicate with each other?
