Some plants have funny leaves like this for no reason at all, just a random thing, and most often at first while it is still trying to figure out what "all this growing thing is about".
Your plant is too young to have any deficiencies and will most likely grow out of it. It should not affect growth rates or anything else, they are just a couple of "funny" leaves. I have seen this many times before and it usually doesn't continue for long, but the plant will usually grow similar leaves every now and then its whole life. I think it is just a genetic "quirk" with some plants.
