Hilfe!!! Was ist das???

I saw this on my current grow. I used my microscope to look at them and the only thing I can guess is that they are trichomes. I haven't looked closely since maybe I will now.

It is a normal leaf. Otherwise what autoflowerssuck said is pretty good advice.

Looks fine... can't wipe away midlew, but this doesn'tlook like that either way. The hyphae or wahtever it is called will still be hooked into the plant if midew is wiped away, it will grow back without any new infection, because it never left. looks like a normal leaf. some hair-like projections, maybe a hint of a trichome here or there. Not all trichomes are capitulated. there's a few different types of varying sizes. The one you probably already recognize in the important one. stalk with head and 50-150 microns in length. wpm will look like a net of fibers coating what you see in the video provided. it won't be individual portruding bits or least not beyond the initial infection, which would be low-probability that you looked at exactly the right moment. wpm would start as a small roundish colony and spreading quickly by the time you can see it (within 3-5 days of infection it is spreading spores). if oyu see a hint of a white blotch, look at leaf on an angle and the light will refelct more of the 'white' color early on than looking perpendicularly to the leaf surface. Hard to miss any established colony. take a peak when you run into it with scope and you'll see it will stand out clearly as different from normal.

It's not trichomes. I can't tell what it is. You do realize that plants, like humans, have tiny hairs all over our bodies, and so do plants if you look close enough. Jesus man, you are paranoid lol. Keep your temp and humidity in check. Keep air moving around. provide some light and some food and water and make sure to pH correctly and don't over water and you'll sleep a lot better lol
