Autos have something in them that's called Ruderails. It comes from a plant in sibera.
Anyways, it makes them mutate sometimes and so on. They kind of have a mind of their own and things like that will be a common thing with autos.
I've had fan leafs grow on top of fan leafs.
Weird growth, in late flowering.
I can go on.
Their autos. Like marmite ppl love or they hate them.
Me, I like em, but even with solid genetics like Dutch you get funnies. OO actually thinking of it. My double fan leaf thing was from my Dutch passion CA.
Good luck.
