Yellow-ish spots on mint

My mint started getting these yellow-ish brown-ish spots. Do you know what's happening?

Re: Yellow-ish spots on mint

It looks like a sucking pest, it might be thrip damage or aphids. The tiny insects are hard to see without magnification. A hand lens would be a good investment. If you look on the underside of the leaf you might see a discoloration. Aphids are bigger and would be easier to spot on the bottom of the leaves. They would be soft and sticky feeling.

Happy gardening in Hawaii. Gardens are where people grow.
