Pumpkin leaf symptoms

Pumpkin    Australia

Hi we have some Australian breed grey pumpkins showing an abnormal leaf pattern btw the cells. No yellowing is evident like common nutrient or disease issues. Has anyone ever seen a similar issue?

I think it is silver leaf symptom caused by white flies feeding. Quite common in cucurbits.
This characteristic pattern occurs due to toxin produced by silver white flies feeding (especially immature stage flies).
