Leaves not looking good

I started these in coco and transfered to DWC for extermination. Noticed a few leaves have this weird looking line. Any idea what this is?






I think leafminers. I’ve not had them in real life but seen pictures

This is correct. Discard those leaves. Pick up some captain jacks dead bug and douse the plant at lights out.

I’d cut off the affected leaves because they’re in there laying eggs

What @BobbyDigital said

Thanks for all the help. I’ll try spraying with the recommendation.

Definitely tracking on the leaf from a Insect.
