holes in leaves

[Coachforlife]

Hi gang,
I found a few leaves with holes in them, see photo, I've not seen any flies, worms or caterpillars. About once a week I've been spraying with Monterey B.t RTU spray (Spinosad) for prevention. Any ideas what is causing the holes. Otherwise, I think the plant looks pretty good.
Thanks.

Leaf hoppers maybe?

For that I wouldn’t spray my plant with spinosad.
it’s green and healthy. It’s normal you will get a bite here and there when growing outside. I get that every year - but I’m definitely not spraying my plant with spinosad just for that.. my opinion

Agree 100%

I'm going with simple damage. Probably happened when they were younger leaves. If you look at the two leaves, the holes are happening symmetrically on each. The brown edges are thicker than they would be if they were getting chomped. Chomped holes have clean edges. Were they bug holes they would also be sporadic. Random.

However, from the resolution on my screen, it looks like you might have spider mites.

Could also be thrips damage? The “snail trail”
I have them right now, it could look like thrips.

Do stop using the spinosad when in flower, it is not safe, it is being banned in many places for our use.
I too think its where another leaf rubbed it and made holes, lady bugs would be a great addition to the grow.
