Tiny holes on new growth

[cornnugget]

One of my plants has these tiny holes on the new growth. I see no bugs (used my loupe to look closely). None of my other plants are doing this.

I suspect the holes might have happened because I misted the plants on a very hot day, and the water droplets plus sun damaged the delicate new growth.

Opinions?

I'm tempted to spray for bugs "just in case", but I don't want to if it's not needed.

Do you have a scope, a loupe or even a simple magnifying glass? Have you checked closely under the leaves?

IMO, looks like Caterpillar/Inchworm damage. You can spray bacillus thuringiensis.

Yeah I checked with a loupe, under leaves and everything

Agree with the above regarding caterpillars. It’s that time of the season. Be sure to check for egg cases, cocoons etc.

I just noticed one of the older leaves has similar spotting but no actual holes.

Insects. Chewers. Again smaller caterpillars or even grasshoppers.

Agree looks like something has been haven a go at your ladies keep an eye out for leaf miners !

Outdoor. Problems with thrips, mites, caterkillers, all ended once I started preventative spraying of spinisad one week, and BT the next through veg and half of flower. Safe and effective....but a PIA.

BT kills when something chews...
Spinisad kills on contact...

What is your opinion on dusting with bonide eight? I just bought some (i live in a rural area and options were limited... I don't want to drive an hour or wait a week for something to be shipped) and dusted my plant.

Now I'm worried I should have held out and just ordered been oil.

Leafhopper damage looks pretty similar, and the spots can turn into holes afterwards. They did on my plant. They'll jump or fly away by the time you get close. Or hide under leaves. I've heard four lined plant bug leaves similar damage, but I've never seen one myself. Insecticidal soap works if you spray them directly, something like Safer's (potassium salts of fatty acids) should be pretty widely available, even in a rural area, it's used to treat some vegetable crops.

Now that you mention it, I did see a little leaf hopper earlier.

At this point I dusted the affected plant with Bonide Eight (which is pyrethrin). I considered dusting all of my plants, but I really would rather not, so I'm going to just keep an eye out for problems. I'll pick up neem oil next time I head to the city, since I'm not thrilled with the fact that pyrethrin is very lethal to bees.

Did you ever figure out what was eating your plants? I believe I discovered the same issue on mine today. I could really use some advice.
