    Default White powdery mildew?

    Hey everybody.
    I have had white ‘bits’ on one of my super Kush’ s for about 2 weeks now, which I think is white powdery mildew. Could people on here give their opinion on what it likely is? If it turns out to be that then I guess il have to harvest early and cut my losses. I’ve attached a image or 2 of the affected Plant. Thanks all

    I doubt it's powdery mildew, but you need to get a picture of it in normal lighting up close as you can. It also wouldn't hurt to take off one of those upper leaves that's really affected and get a shot of the underside of that leaf.

    I'm leaning more towards bug damage, but we won't really know until you get some better pictures on a different light.

    Very tricky...can you do a light off picture?

    My first thought is mites, I’m afraid.

    Sorry about bad pics.. here are some taken without lights on. Also looking at it now it may not be wpm but if its mites then il have to do something about it. If its mites is it okay to keep rather than harvest early ? Thanks all for your answers.

    Well it sure does look like mites and usually do want to treat them, but you're far enough along in flower I would be hesitant to spray anything.

    On the bright side, you are far enough along in flower that you should be able to finish it without too much difficulty.

    What do the rest of your buds look like? If they all have their pistils dying back and calyxs swelling then you're pretty close to harvest.

    From your advice I should be able to keep it flowering longer then. Il stay away from sprays as suggested. I've attached a pic of one of the lower bud sites, theres still some wispy hairs but should be ready in no more than 3 weeks. I Appreciate your opinion

    I use a digital microscope that goes to 1000X on all my vegetable, flower and now my pot plant.

    Takes out the guesswork.

    Amazon around 20 dollars.

    Guessing is bad...Very, very, bad...LOL

    Good Luck
