It's not a nute issue... I think you may have a bug of some kind but I'm not sure. Have you looked underneath the leaves?

Small white spots on leaves in germination phase.
Does anybody know if those small white spots are ok? I have water 7 pH and I add some citric acid to lower it to 6 pH, when I sprinkle the soil I lightly sprinkle the leaves as well and I'm not sure if it's the effect of dry citric acid or something else. Thanks.

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?

What are your best experiences for treating white powdery mildew? (4th week of flower)
I carefully removed all the leaves with WM on it, but i want to spray the leaves to hinder further development of the mildew. What are your best experiences? I've read about milk solution, maybe citric acid solution with a ph of 9? Can i spray the buds too? Thanks for your help!

Best treatment for combating white powdery mildew at first sign of it? I used a non toxic sulfur spray with some defoliation of the more prominent leaves, especially any close to a bud site. It helped keep it at bay but had to be reapplied weekly and still fighting it daily.

Help the Hermy
My worst nightmare has become reality, my Pineapple Chunck (Week 7 of Flower) has developed male pollen sacs. What is your advice for me now? Remove the whole plant? Cut off branches? Harvest the plant now? The other plants are showing no signs, but I'm afraid it will be seedy 😵

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?

White Spots on top of Leaves
I have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?

Spider mites?
My partner just cut some clones off of a pre-flowering plant & put them in a root rain spray cloned. Been 2 days since he cut the clones. No roots yet but he’s wondering if he has spider mites & if so what he should do. Do you all notice anything wrong?

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?

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?

Minor damage to a few leaves found today - what is it?
I am trying to determine the cause of damage to a few leaves that was observed this week. It may be two different problems. On a few leaves, I see brown spots which may have originally been white. On another 2 leaves, I see a burn hole through the leaves with brown edges.
