Help with holes in leafs

Growing indoor
Watering every 3-4 days depending on dryness
Fox farm happy frog 1 galling pots only feed nutes once at 1/3 strength in week 2
First day of week 3
Spider farmer light at 60% about 16-18” away

just noticed holes for first time yesterday, I have seen no pests anywhere on the plants. I haven’t seen any caterpillar droppings near the holes.
I have an oscillating fan in the far corner away from it and there is a clip fan maybe a foot away and 4” above the plant. The fan isn’t blowing directly on the plant from what I can tell. 4 other plants in the tent are all smaller and none have holes or marks

I have the exact same issue
Did you find out what it was? Did you end up with more issues?

Do you foliar feed? Sometimes the water droplets act like a magnifying lens and it can create holes if left in direct light not even foliar feed maybe you got a couple drops of water on the plant while feeding....I'd be care ful when watering if it keeps happening you know it's something else I don't think it's a pest problem

What's you humidity and temps at ? You have some twisted/curling leaves

Yes but not crazy bad just a few, i figure due to LST. Ive viewed 60x and dont see any pests
I figured maybe the plant or just mother nature?
Only a few leaves are like this everything else looks fine
72-75 degrees
Ru 55-60
My light is close though. Like 15"
Its an led but i have adjusted for the closeness (as best as i can)

Spider farmer lights distance is 18-24inches minimal in veg...12 inches in flower...

Have you checked under the leaves for pest some hide there but honestly I think it was from water in the leaves and maybe it light was a little close...see what happens this week give us a update if it keeps spreading then you probably have a pest problem

I had the same exact thing happen last grow not bad only a couple spots I just ruled it out to be the light hitting the water or leaf deformity but it never really spread....I was also foliar feeding so I figured it was the water magnifying the light...
