Is this powdery mildew?

zacwazstarted grow question a year ago

I just noticed this tiny white spot on a leaf of two different plants and having trouble ID’ing it. It doesn’t seem powdery or fuzzy and almost looks like a mineral deposit… but I really have no clue. Appreciate any ideas—thanks!

Probably just some nutes that dripped on the leaf... have you tried to wipe it off with a damp cloth? It certainly doesn't look like a nute issue nor does it look like WPM... I wouldn't worry about it myself... good luck!

No , not WPM - this is likely something dried on there. Wet your finger and I’d bet ya it rubs right off

White powdery mildew in late flower What's your best remedy to remove it on flowering plants? I just found it after I had forgotten to replace on of the fans when I left them for a few days. What can I do to remove it as quickly as possible without ruining the buds? I'd prefer not spraying them with milk.

Is this powdery mildew?Is this powdery mildew? I am seeing some white spots starting to form on the underside and top side of lower fan leaves. Would adding an oscillating fan help prevent anymore white spots from appearing in the future or will I need to apply neem oil or something?

Possible mold/mildew - I ask a ton of grow questions but figure someone else might learn if I do well or f up. Good community here Mildew? This has been on certain leaves of my plants since I got them so I didn't think much of them. But as I'm about two weeks into flowering, I want to see if this is possibly an issue. Have okay airflow in the tent but could be better. Humidity is 55% atmosphere. Thoughts?

I need help diagnosing what this was. I already cut off two of the affected leaves on the Kmintz, but other leaves have small amount of the same substance on both plants. The brown spot in the first pic ended up turning into a hole because it was so dry. Is this powdery mildew?
