What’s Going on with my Diffenbachia?

what is happening with this stem? This is the newest leaf. I notice when it first started to unfurl it looked kind of weird at the base of the leaf. After it unfurl about a week later I notice how it looks now. It has actual spread, the area was not that large when I first noticed it. It gets watered about every 7-10 day, in a fast draining soil. Fertilizer, Diluted strength when I do water. Have not noticed any pest, plant was sprayed proactively about 3 weeks ago. I propagated this last September and it has been doing fine, don’t know what to think, maybe that stem has to go as you can see, there is a new leaf. Thanks
