Hi!

Can someone please tell me if I have WPM? I had a little bit of it early on but since contained it. I know it is systematic and doesn't completely go away. Im in the early stages of flowering with my outdoor plants. I took off one of the popcorn buds and took some pictures with and without the microscope... check it out...

I think I see PM in your third pic. I believe the fiberous looking strands are the PM, not trichs.

Thanks for the heads up... take a look at this pic. The trichs look a bit fiberous maybe they are just trichs??
I'm trying to give myself the benefit of the doubt lol

Thats really looking like PM. Trichs have a long stem with a bulb on top that stand up. Those are laying down with no bulbs on the tops and there are way too many of them in your last 2 pics. :(

Those look like stem hairs.

Powdery mildew grows in spores, i'd imagine since thats what it is and thats what it looks like from the eye.

Fuzz is mold. But I maintain that looks like stem hairs from where he broke the nug off the stalk. Normal IMO.

Try SM-90. It's less than $20. It got rid of all of the mildew on my leaves. Organic and no adverse effects to the plant. Just treat now before the PM gets worse

I don't want to spray anything on it if I don't have to. I'm going to try to spot treat. Last time I had pm was my first grow. I sprayed I think it was baking soda mixed with water. I think it was supposed to throw off the ph and kill the pm but it just made the buds not burn right. It turned black and never turned to ash.
 
Hydrogen peroxide & water. No funny smells, tastes or byproducts. Harmless to plants and destroys PM on contact.

When applied to the plant, the chemical's two oxygen atoms attach to the fungus and oxidize or burn it. While stronger concentrations can be purchased at garden centers containing 10 to 27 percent hp mixed with other ingredients, the household bottle containing 3 to 9 percent is adequate to kill various types of plant fungus without leaving any damaging residue.

Mix 1 pint of water with 4 to 5 tablespoons of household hydrogen peroxide (3 to 9 percent strength) in a spray bottle. Shake to mix thoroughly, and spray it on the affected plant daily. Once the fungus disappears, you may continue to spray the plant daily to avoid its return.
After the H2o2 has been used, the only byproduct of it is water.
