Help me! I’m a new grower and I have this massive outbreak of white powdery mildew on my brand new nl autoflowers I have no idea what to do or what caused the issue. My humidity readings are between 76% and 82% because they are still in seedling mode but I first noticed signs around 5 days ago. Is there any way to stop this from taking over? It’s so early in my grow this is my second go around and my last go I had an issue w powdery mildew as well. Please leave any remedies you know to get rid of this.

That's not powdery mildew imo, looks like a layer of mold from soil being too wet and not enough air circulation in your tent. I've had this in the past and just taken it out and replaced with fresh soil

I have to agree looks like mold to me as well. You want to get them transplanted ASAP

That looks like mycelium, which is a beneficial fungi. Are you growing organically?

I'm doing the organic thing, and at first I was panicking seeing what looked like mold growing on top of the soil, and technically it is a fungus, but so is mycorrhizae. Some organic amendments will grow the mycelium much faster, like bokashi.

Does it look like this?

Mycelium

Fungi often develop long threads which carry on subdividing. This can lead to an extensive underground network. That can be extremely useful to all kinds of plants and animals.

By the way I’m growing in coco coir not organics using the canna coco formula. Also at the stage in life how would I properly transplant them without shocking or damaging them

I spray my surface soil with 6% H2O2 "Hydrogen Peroxide". Just enough to wet the surface. After 2 days it is usually gone. Just scrape the top 1" of soil and mix it in. Less water. More air circulation. I get this once in awhile when I get too crowded in my tent with starters.
