Number of Leafs

Sorry for the newb question but I have 3-4 ladies that only have 3 leafs per fan and the rest of the crew have 5 leafs??? Anything that I should worry about anything I should know about? RESPECT

could be different strains , some plants [most] start with three then go to five-then-7 then -9......

No need to worry. But what you do need to know is that a plant is like a woman. Treat her nicely and you'll see she was just shy. She'll show you what she's made of soon enough.
