Cucumber Plant Leaf Symptoms

Question

Hi, My cucumber plants look healthy overall and are mature and producing Cucumbers. However, I recently started to notice these leaf symptoms. I hope its not a virus? Maybe Insects? I’ve been spraying Spinosad and Hort oil as a preventative. If it is a disease are cucumbers safe so long as they look ok? Thanks! Sam

This is the start of magnesium deficiency. Correcting this early is pretty easy, though.
