Livistonia Chinensis wrinkles

[Keys6505]

When I initially landscaped my yard I purchased 5 Livistonia Chinensis, one of which is about 15' tall and the other 4 were only about 2' tall to the top of the highest fan.  Out of the 5, four have the typical flat-ish leaf of a Chinensis while the fifth seems to have a few wrinkles in all of the leaves.  The wrinkles are present in new leaves and remains after they fully open up.  Is this just a natural variation or a sign of some type of nutrient deficiency?  It's kind of hard to see in the photos but it zig zags with the low points dead center opposite the petiole and on either side.

Looks perfectly fine to me.  If you are referring to the wrinkles on the leaf near the fence in the last pic I wouldn't worry about it.  Yours looks good!  Young chinensis leaves often don't split open up that much.  Here is mine about the same size:
