Hi guys, i have this brown spots on my monstera. I tried to wipe the leaf that are affected with clean wet cloth and it appears that theres some kind of brown dust. So im thinking this might be due to rust fungus. But does anyone have more diagnose? Please helpp!

You have thrips. You can treat by sprinkling a systemic (if available in your area—I use Bonide Systemic Granules) into the soil and it will absorb into the plant with every watering. Lasts about 4-6 weeks. The insecticide will poison the thrips and any new larvae will die.
