White spots on leaves
RollinRick
started grow question 5y ago
There are some white spots appearing on my leaves on a couple plants in the same tent? All are at varying stages of life, but one - which has not flowered (probably a photoperiod) doesn't have the same.

Looks like spider mite infestation. I use microbes to kill pest. My favorite for spider mite is Beauvaria bassiana.

White Spots on top of Leaves
I 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?

When using a Apple cider vinegar/water mixture is it ok to spray the entire plant, leaves bud and all to combat Powdery Mildew (PM)? I’m assuming it’s ok and may help prevent the PM from infecting the buds leading to bud rot?

Bagnare foglie
Ciao 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 mille

Does White Powdery Mildew brush off easily
Does white powdery mold brush off? Found some white stuff on my leaves but it easily came off with my finger or some water, its possible that the spots are minerals or something from my water or leftover nutes because I havent been able to get under theleaves to water.

Powdery Mildew near end of flowering
For the last few days, powdery mildew is starting to form on the leaves and some of the buds. I've cut where mildew was, lowered humidity to around 45% and increased air circulation by focusing a fan on the plant but it is still forming. Anything else I should do?

I have noticed small powdery mildew spots on my pineapple express plant. The soil usually feels pretty dry so i don't think it is due to overwatering. I put them inside at night due to humidity outside. Should I separate this plant from the rest?
