Light bleach or defficiency?

My other plants dont dont have this, i am growing under a led light, is this light bleach or some difficiency.

About 3 weeks into veg, no nutes given yes as the soil has some mixed in from factory.

Other than these spots the plants are perky and have no other issues.

Can anyone shed some light on this?

Kind regards

Is that coco?

No its just regular bagged soil with nutes in them, had some nute burn in the early beginning but they outgrew that.

I don’t see any vermiculite in there for drainage?

The soil is allready premixed with additives for drainage and water and oxygen retainment. So i didnt mix anything extra in, its just these 2 leaves out of 5 plants with the spots. The small amount of droopinf is because it is revovering from transplant shock.

I wouldn’t worry about it.

Looks like thrip damage and mag deficiency.

Do you foliar feed? If you do so under strong enough light intensity it can make circular spots on the leaves like that as well. If not it’s a nute deficiency or root growth issue.
