Yes it is mildew the best way i like to get rid of it is to add some air rotation like a fan or some sort and watch my watering to much water can really be a bummer with high humidity.

White residue - Mildew or Sugar?
Plants are giving off strong plant like smell rather than bud smell. Almost chlorophyll or ammonia like. Is the white residue on the leaves signs of mildew or does it look healthy and it's just sugar?

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?

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?

Mould? Mites? Nothing?
OK, re asking this question with better photos as I don't know how to add new photos to an already posted question. Posssible mold? Spider mites? Leaves have looked kinda similar since I got them. Any ideas? To me it looks like maybe mites but I dunnno.

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?

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.

PM or Nah?
Noticed some white spots on the tops of a few leaves. I’m days away from chopping and I’m wondering if it’s PM. If it is, what’s the best action to take at this point?

Powdery Mildew near end of flowering
For the last few days, powdery mildew is starting to form on the leaves and some of the buds. I've cut where mildew was, lowered humidity to around 45% and increased air circulation by focusing a fan on the plant but it is still forming. Anything else I should do?
