idont worry... its just a sign of the next stage in the evolution of cannabis...

ive seen leaves with full pot leaves (5-7 leaflets) growing where the leaflets growing where the leaflets would normally be. it was some crazy looking pot. and in high times or cannabis culture (cant remember which) there was a picture of a leaf growing out of the center of another leaf.

Ive even seen a 21 leaved pot leaf before.
