White powdery mildew
BufoAlvarez
started grow question 6y ago
I’m still unsure if it’s white powdery mildew or dust or my dandruff or what? It’s early if it is, ive already treated with apple cider vinegar 1 time. I’m going to share a video and pictures of them to see if anyone can confirm. Thanks in advance

Powdery mildew? is there an organic way to treat it? Milk? mild vinegar solution I have tried the milk spray. It may have knocked it back a little but i'm pulling leaves every day and keeping a close eye out for it.

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?

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?

Ok folks, went out to check the trichomes and smelled something funny...like mold. Saw these spots on several leaves and now I'm panicking so close to harvest. Let me know what you think and what I can do about it, if anything. Thanks!!

White powder on leaves
Got like a white powder on my leaves on one plant veg stage. Thinking it's some kind of mold but it's only on one plant out of 10 in 4x4 tent . Getting more & more of it but staying in that one plant..I moved her around so she'd get more wind. 2 weeks before she goes outside

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?

My blue widow has some white spot on some leave and I think it could be a mushroo but I don't know what to do, she also has her leaves that are going down but I think that's just a lack of water because the weather was very hot this week, some leaves are also turning yellow

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.

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 😵

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?

When using a Apple cider vinegar/water mixture is it ok to spray the entire plant, leaves bud and all to combat Powdery Mildew (PM)? I’m assuming it’s ok and may help prevent the PM from infecting the buds leading to bud rot?

Bagnare foglie
Hey everyone. Yesterday I sprayed neem oil and there are some drops left on the leaves leaving a white powder. Can I spray just water on the leaves with the lights on (24-hour cycle) to try to wash away these residues, or will I burn the leaves by wetting them? Thanks a lot!
