Some type of infestation?

[Buzzy]

I noticed a few leaves that look partially chewed today, and a long hole/crack in a large leaf. Leaves are drooping but I heavily watered a few hours ago.
This is only my 4th indoor grow and the first problem I've encountered.

I put 2 drops of DAWN in my misting bottle and saturated all 4 plants leaves, top and bottom. I hope this does the trick. My eyesight is poor and I could not see a speck or a bug.

Sound familiar to anybody? I'm clueless.

In retrospect the few ragged ended leaves I saw were likely due to me FIMMING all 4 plants Saturday night.

I'm a dumbazz.
