Hi I found this plant in a canola trial which has extensive discolouration on leaves. No visible pest damage no stunted growth and has been given adequate macro nutrients. This is the only plant in the trial with any sort of discolouration. Thoughts?

Hi. This is something that occasionally happens to an individual canola plant and is similar to what happens in variegated plants in the nursery industry. It is nothing to worry about and wont affect the rest of the trial site.
