12 leaflets??? wtf

Hey hey! Im just in about the 4th week of vegg. and two of my plants have devoloped 12 leaflets.. 1 leaflet growing ontop op the largest leaflets.. its not just one set of leafs, its a continous of both.. i have 4 different strains, and the two that makes the phenomenon are from same strain.. i just couldnt find anything about.. well.. just wanted to here if its a crazy mutation or if its a normal thing..

The picture i have uploaded is from 2 days ago, and it has only 10 leafslets.. but still an even number showing the rtard growth..

That's crazy but not unheard of at all. I've had leaves that were not even serrated, just straight edged. The fan leaves are just solar panels anyway.
