I noticed these white dots on the tips of two bottom fan leaves. There aren't any others and have found no evidence of mites, thrips or other pests. Anyone know what this is? Is it mildew/mold of some kind?
On my PPD auto that just entered flower.

that's more zoomed in.. imagine that coating over the trichomes. over surface of leaf....
it'll start as a roundish colony and expand. by the time you see it it is probably propagating itself (reproducing/spreading through air). It's very discernable from normal leaves and bud material.
Too uniformed to be thrips but besides that I haven't got a clue. Could you not find any images on google. I doubt its mildew if your plants are healthy with a healthy environment. I'll take a look.
