White spots on leaves

RollinRickstarted grow question 5y ago

There are some white spots appearing on my leaves on a couple plants in the same tent? All are at varying stages of life, but one - which has not flowered (probably a photoperiod) doesn't have the same.

Looks like spider mite infestation. I use microbes to kill pest. My favorite for spider mite is Beauvaria bassiana.

Currently only discovered in those two spots seen on the picture. In pics I find from mildew, it usually starts more dusty.. I also made one picture under the micro.

Pollen sacks or powdery mildew?I noticed what I thought was powdery mildew on a leaf, then noticed funny looking things right next to the powder.

Powdery mildew or just... chalk?Can someone confirm if this is powdery mildew or just chalk from misting, please? The walls of the grow tent had a little chalk on them too so that's why I am not a 100% sure. Temperatures have been quite optimal for late flower and humidity has not even been over 40%.

White Powder on Leaf Here's a closer shot of the white powdery stuff, only on one leaf right now. I'm going to keep an eye on it and try not to worry for now. If I suspect it's mildew, mold, or Fungus I will take action. What does it look like it could be to you all?
