Been growing indoors for a long time. First outdoor. Powder mildew?

[Illbill]

I’ve been growing a long time. Haven’t really run into any problems when it comes to mold or powder mildew. This to me, looks like the beginning of powder mildew. I have a whole plant pic. My dog behind it is 100 pounds if it helps to get a feel on the size of the plant. They’re just over a month old and it’s on both of them. I’m in Ohio and it’s been pretty rainy but it’s been better in the last month. They’re real and stretchy so they get plenty of airflow.

It does look like white powdery mildew. It's easy to treat. I used a milk solution, and it worked quite well.

Just that one spot? Maybe a bird shit on it, then get partially washed away by rain?

I thought bird shit, too, until the OP mentioned rainy weather. It might be because, well, shit happens. It looks a lot like the WPM I dealt with a few grows back, though, and there weren't any birds in my tent.

I’ll be reading up on it and trying it.

There’s about 20 spots on a few different leaves. I tried wiping it off

Probably spread it by doing so. No worries, there's plenty of treatments that work. Personally I use neem oil

to control the PM and moth larvae as well as aphids and spider mites. If you go the milk route be sure to use no fat as the fat in milk will smell pretty bad after a few days


Moth larvae can destroy all the buds on a plant. Ever see white or yellowish butterflies fluttering around your garden?

We call them Cabbage moths and they will lay eggs that will hatch into larvae and eat the flower stems killing the bud which will be drying and turning brown while you're waiting for your plant to finish. And these stelthy bastards

Will really do a number on your plants. Bt

Bacillus thuringiensis is good for them as well.

You've got a lot more critters outside then you can imagine and you really need an Integrated Pest Management (IPM) system to protect your plants from insects and disease. You need to take some time now before more problems arise. If moth larvae are munching on your flower stems you won't know about it until the flower dries up so NOW is the time to figure out how you'll treat your plants to get them finished.

Pretty much kills most insects including ants but don't want to use it too often. Follow all directions on lables of any and all insecticides but this is a good start on what you might need going forward

I just wiped the spot I took a pic of. I washed my hands after just in case. I took the pic after it dried.

I actually have some Neem oil laying around. I’ll probably spray with that. Should I spray the spots or the whole plant minus the buds?

Whole plant undersides too. Do it after sundown or the oil will scorch the leaves.
