Thanks Bananaman, Gabe,
I bought this plant a year ago, it overwintered inside and continually grew. They plant you see today is actually a pup from spring, the parent broke when another plant fell on top of it. I transplanted it about 2 months ago, I know the pot looks big for its size but, its mat needed a bigger container, roots were poking out every which way. I have fertilized it once or twice since repotting with MG all-purpose very dilluted (says to use 1/2 teaspoon per gallon, I use 1/2 teaspoon per 5 gallons) Perhaps drought may be indicated rather than overwater? I believe I let it dry a few times as I was afraid the soil was holding too much water.
Let me show you the morse code and streak areas on the Dwarf Cav.
This is the first leaf to show this, about the 5th leaf on the pstem. Top of leaf view.
Notice the white streaks and the white spot.
This is the bottom view. You can see the rest of the leaf is normal.
This is another leaf, showing the same symptoms. Left side of the leaf is normal, right side has morse code.
Another angle.
This is the newest leaf, with symptoms becoming visible.
