Thank you for the information @Caligurl. I thought I would repost it if others didn’t know like I did.
It is 100% thrip damage. they are very tiny… you need a scope to see them. The light areas are from them sucking on the leaves and the black stuff is their poop. You’ll need to spray for 4 days straight, then once a week as a pest management too.
Thrips can also live in the soil, particularly during their larval stage. To eliminate thrips in the soil, you can use diatomaceous earth or spinosad (as a soil drench).
you have to target thrips at all stages of their life cycle, is why I recommend at least 4 days straight of treatment.
Thrips have a brief life cycle, with adults surviving for approximately 30 days. During this period, a female can deposit between 80 and 300 eggs within plant tissues. These eggs hatch within a few days, and the larvae descend to the soil, where they consume organic matter and occasionally attack plant roots. After pupating, they emerge as adult thrips and continue the cycle on the plant itself.
