So all the images i found on google images about powdery mildew shows it on the leaves. I got this kinda creamy looking gunk on the stem at the bottom and where i topped it few spots.

Is this mildew? Do i just wipe it off or spray with something?

It started at the base of the plant near hydroton rocks.

Its actually a bit hard now. It was goey last time i checked. But i can still scrape it off with my finger.

Just checking with experts before i start spraying it with random stuff. Its my first grow.

That's normal. It's just how the skin grows on the stalks on some plants.

Edit: I see what you mean now at the base of the plant, almost looks like Mycorrhizae fuzz. Are you using any microbial inoculants?

Just nutes and hydroguard in dwc.

Its a high heat, high humidity environment although im managing that with aircon most of the time, but there are times in a day when i turn the aircon off. Humidity goes to 70% and temperature 28c in the tent.

Not sure what it is but its definitely not plant matter. Looks harmless tho.
