How do you know it, FOR SURE ?

Nope.
Let's see entire plant, please.
In pot or ground?

Those are not the classic leaves of CMV (tightly rolled, string leaves). Nor is it the lime green mottling of TMV (which is a very uncommon disease anyway in the US).

The mottled appearance and the otherwise overall healthy appearance of the leaves is more like early mildew or a micro-nutrient deficiency, probably manganese and magnesium.

This is based on just the pic. Would need more info on plant and a photo of it as a whole to be sure.

Actually since I took the pic it has grown rapidly and the new growth does not have the pattern. It seems to be mostly at the bottom now on the old growth so whatever it is it looks like it is growing out of it. Strange that it is the only one. I was ready to pull it. seysonn, I was asking a question not making a statement.
