Yes, this happens from time to time and is not a reason for concern. Once you have been growing for a while, you will see all sorts of strange growths like this and many more strange things. I have had self topping plants like yours, that have grown 4 leaves and no branches at the nodes, with 2 normal leaves and 2 leaves with either 1, 2 or three blades. Then the next node or two will be normal and then the next node having one branch only or 2 leaves no branches, 2 branches and 3 leaves etc etc. The plants have always flowered normally and with normal buds.

Your main cola has grown off to the left, the fan leaf is supposed to below that side shoot. It's happened to me before and she grew ok still. I just put it down to a dodgy phenotype.
