Strain related?

So this girl here ever since like her 3-4 node has been growing some weird leafs. She consistantly develops even number leafs. Mostly 10's. Some 12's. Not only that a few sets of leaves are deformed. Do I have an issue here or is it just the genetics. It's Chemdog grown in ground

Strain phenomena?
Other may chime in but overall looks ok to me
