Just noticed this all over my cucumber leaves. I've grown cucumber before but never had this issue. Will it affect the plants growth and how can I fix it?
Hello.. Any chance you could have got water droplets on the leaves in bright sunshine? It looks like scorch.. Have you checked under the leaves for any aphids as they suck sap and cause similar marks. If it's just leaf scorch it shouldn't affect growth or cropping. Good luck.
