I spotted a Cryptocoryne spotting similar "light vein" patterns among a healthy bunch of C. pontederiifolia during one field trip a few months ago.

This is a close up view of that single plant in my emersed tank.

For a few months, every new leaves that emerged had the "light vein" patterns until recently, I found that the newer leaves no longer have such patterns and the older leaves markings are getting less and less apparant. I have try to post a updated photograph of that plant now tonight when I reach home.
Conclusion for my case: likely a nutrient problem.

Yeap, it may caused by dozens of weird reasons, but frankly its doesn't fancy me
It does have flowers but I'm not showing them.
Clue: its the same species as the plants arund
Plant collected on beginning of this year (same pattern), all leaves are newly grown, and so do the neighbour plants. I don't even remember he told me he found this plant months ago until he show me the photos. Nothing fancy, but lets have some fun guessing...
I do agree with you that it may caused by nutrient problem
As promised, this is how the C. pontederiifolia looks like now after 5 months, the "light vein" pattern is no longer apparent for the new leaves.
