Leaf stems splitting open. Help appreciated

I am noticing a couple leaf stems are splitting right open . From the start of the node to the base of the leaf. Only on the tops of the stems though. It does not go right through. It is happening on 2 separate plants. The leafs that have this split, still look very healthy and the split still looks healthy. Not dry or discolored. Just split right open . The biggest splits are on the bottom leaf stems but I do notice that smaller leafs are starting to do this as well. Maybe genetics or I have not a clue.Anyone ever see this?

split? like there is a gap in between the split? can you see through the middle of the split ? sounds crazy or im just to high to understand, give pics it sounds interesting. Ive seen a dip in the top of the leaf stems before but wouldn't call it a split.

yeah bro thats fucking weird post sum pics

ok he say in the first post it does not go all the way through. I have seen this before on a few of my plants, its normal. maybe a genetic thing. not a bad thing at all.
