@OhanaFarmer looks like the start of some insect damage. Likely larvae that just hatched under that leaf. It could either be leaf miner maggots (the larvae of the leaf miner fly) or some other type of pest like certain beetles or moths.

I see what appear to be some tiny green larvae on the underside of the leaves so it’s either the leaf miner maggots or caterpillars/loopers that are just beginning to hatch.

@OhanaFarmer best bet for treatment is to remove the affected leaves and search for eggs over the rest of the plant.

Use some organic insecticidal soap and make sure to get the top and underside of the leaves as well as the stem.

Aside from essential oils and companion plants if you’re growing indoor proper airflow will help mitigate a lot of pest problems because the flying pests (like moths, butterflies, and some of the larger flies) can’t sit still long enough to lay their eggs if a fan is always blowing them away.

I removed 2 leaves, did not see any other signs, eggs, or otherwise. Applied soap. So far so good. Thanks for the help!
