Small dots on leafs

[Darthweeder]

Hi!

Can't seem to find an answer to my issue.
Got between 26-30 degrees Celsius and 40ish humidity.
A oscillating on for 10 minutes every hour.
BUT, noticed today that the fan has been off for 1-2 days maybe.

Using biobizz nuts:
Root juice
Grow
Heaven
Alg a mic.

What could this be?

The leafs are and have been yellow, which I have been guessing is overwatering. But the small small spots is something new.

Hey Cookie,

why do you only 10 min of the fan? plants need aerotation the entire life cycle, when lights are on i give my plants wind that makes bounce, when lights off my fans running lower.
Some further infos would be nice: how old are they? unfortunately ca't seed any dots, but it's maybe because i view on mobile

Well.. The fan is kinda big and I thought that letting it go on and off would be enough.

But I think it might be wpm, not sure.

*edit
I've changed the fan to be on 24h now and sprayed them with milk/water.

They are 3-5 weeks old.

Can you get some clearer shots under natural light of the dots? and by uploading click full image!

....I need normal light pics mate, HPS is hopeless for diagnostics,...
