Is this leaf miner damage? If so how do I get rid of it
Sure looks like leaf miners to me.
There are manual ways by smooshing them by squeezing the leaves.
Manually remove the leaves and dispose of them.
And there are biological sprays you can use too.
Spinosad is one that is used. Captain jacks dead bug is a product that contains it.
Hope this helps
Captain Jack’s Deadbug and Safer (Bacillus Thurengiensis) both do a great job. I would institute a program right away if you have bugs. I spray straight 3% peroxide on my plants, wait 48 hours then spray with one of the two products above. Wait five days then repeat with peroxide/bacteria. I do this throughout the grow to prevent them getting established.
