This attached photo is a leaf from a eureka lemon tree that I recently purchased from an online store. Also have a navelina orange tree with exactly the same problem.
Initially one or two leaves had this but this has now spread to most/all of the leaves.
Have looked at various times (day/night) and not been able to see any bug that is doing this
I have tried spraying soapy water and Bayer Provado ultimate bug killer and this does not seem to have helped (2-3 weeks).
Does anyone have any idea what this could be and how to resolve ?
