Are these Thrips?

[TommyT]

Is this leaf damage caused by Thrips?

really hard to tell purely from damage mate. ya really need to try find one if there is something moving around

from the lay of the blemishes tho it doesnt look like pests ive seen.... any chance its just salt dried onto the leaf?

[TommyT]

I haven't seen ANY bugs. That's why I'm questioning it. I know thrips are really small. I don't foliar feed so I'm not sure if it's salt or not. Could something like this be caused by overfertilization?
It's hard to tell from the picture but those little black pock marks look like little holes in the leaves.

lick your finger and give it a rub

if it comes off your all good bud. over ferts a tricky one. its just what salts do when there is evaporation

i had a similar problem but didnt find any bugs a few grows back

Thrips normally eat in short, straight lines. I'd like to see a closer image of the damage. From a distance, it looks like mites, but it's hard to tell atm.

I you do see thrips, they are quite long and slender.

It doesn't seem to come off.

I can't see ANY bugs. With the microscope or anything.

I can't see any webs.

The plants that are affected are in veg stage.
So I did spray them down with https://bonide.com/product/captain-jacks-dbb-rtu/
I will spray them again in 7 days to try to break the cycle.
Supposedly the thrips and eggs can't live without living plants or dead plant material.
They lay eggs on the leaves so I wonder if I need to replace my soil or just spray it down with pyrethrins.
I won't start any new plants. Once everything is out of my groom I will leave it empty for at least a week and clean everything thoroughly.

@MrNice Thanks for taking the time and digging up the pictures for me.
Your leaf looks somewhat uniformly speckled and mine looks like randomly placed spots. This is on about half the leaves on several different plants of different strains.

Yeah there is nothing on the bottom side of the leaf. You can't see the white spots or the little black pock marks on the underside.
