My greenhouse squash plants have developed some wrinkled yellow leaves.... Started with one and now all 4 are showing the same pattern ie patches of yellow and light green on the new leaves with brown edges... Could be mosaic virus but am I mising anything else obvious? And any tips to sort them out would help.. I'd like to avoid chucking the lot

Ill try and post some pics

Is the greenhouse heated? Could they just have got cold? It is rather early days yet. Another month at least before mine go in.

it is a heated greenhouse but theyre not been put in there yet... just started a few early to get started in my light room... temperature control is pretty constant..
Have had a close look at the leaves affected... The yellowing seems to originate from the leaf veins and on the underside of the leaves there are pin prick sized green balls attached to the affected veins...Can't quite make them out but might be aphids...
