This is my 2nd year in my greenhouse and both years I have had cucumber issues. I thought it was too much direct sunlight and this year I'm being told I need to use CalMag. I have attached pictures of multiple varieties of my cucumbers with the problem. I was thinking it is cucumber mosaic virus but some of my seeds say they are resistant. I have everything on a drip line irrigation system with a fertilizer injector and use CalMag plus every 2 weeks in addition by hand watering.
My varieties are straight 8, lemon, garden sweet, pickle bush, and space master.
Not every cucumber plant looks like this bit half of them do.

Does anyone have ideas on the issue and how to remedy it? Thank you so much.

Welcome to the forum!!! I'm no expert but the yellow leaves with green veins is apparently called "interveinal chlorosis" which is a symptom of an underlying condition.

Not saying that this is the problem but you might want to look at this webpage: https://aggie-horticulture.tam...

Not a great pictorial, but this webpage has some good text info in it regarding things that cause chlorosis: https://gardeningvibe.com/cucu...

Best wishes,
