Number of Leafs

A few of my babies have 3 leafs per fan and others have 5! Should I be worried is there something I need to know? Help a newb out

I had some that had several variations of leaf patterns, It's their genetics. I have some that have 1 leaf on the 2nd node and some that have 5. I have some that have 3 on the second node and then 7 on the 3rd. It's their genetics....

the bigger (older) they get the more they'll have on every leaf. i've seen them up to 11. how old is the plant?

The more the leafs the more sativa it is... yes??

NO....I have an in dica with 13...........most plants start with 3 then 5 then 7 then 9 and so on.......
