White Spots on top of LeavesI have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?Leaves. White powder

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.6y ago

Bagnare foglieCiao a tutti. Ieri ho spruzzato neem oil ed è rimasta qualche goccia nelle foglie lasciando della polverina bianca. Posso spruzzare sopra le foglie solo con dell'acqua con le luci accese(ciclo h24), per cercare di tirare via questi resti o brucerò le foglie bagnando? Grazie milleWeek 2

White powderI've been noticing some sort of white dust on the bottom leaves and stem.
I wiped them off with a kitchen towel with water 2 days ago, but i noticed today that they are back.
They look like cigarette aches. I'm not sure if it's powdery mildew.
I'm not sure it's visible in the picWeek 7

Small white spots on leaves in germination phase.Does anybody know if those small white spots are ok? I have water 7 pH and I add some citric acid to lower it to 6 pH, when I sprinkle the soil I lightly sprinkle the leaves as well and I'm not sure if it's the effect of dry citric acid or something else. Thanks.Leaves. White powder

I've had issues with PM in the past. Safers brand 3 in 1 seems to work temporarily but it always comes back. Also seems like it may deteriorate the trichomes on a flowering plant. RH 50%
I currently am using a worm casting foliar spray and all is staying well. Any more tips?Week 3
