Looks like spider mites. Check the underside of the leaves for mites and eggs.

Definitely flush them out
What nutrients are you using?
EC?
PH?
Temps?

I'm using miracle grow soil, not added any nutrients, pH is fine, temp 28, humidity between 40-60, using two 300w led lights and good air flow. 3 plants are fine while the other 3 have this problem.

Where the 3 that have it sitting close together? It looks like some sort of insect attack to me. Familiar too but i cant put my finger on it. They look pretty healthy otherwise. Id maybe spray with an organic pesticide and go from there. Good luck mate.

Just been thinking,
It looks like something I’ve seen on outdoor grown plants and young plants too like yours.
