Powdery mildew on my leaves - neem oil straight?

[rr14]

Hi there. I just read the guide to the sick plants. It mentions the use of neem oil for powdery mildew. I previously had used some stuff intended for roses that I got from lowes. It worked okay last time I had a breakout. The powdery mildew is on the leaves of my plants. It's not widespread, just here and there. Plants are in the 3rd week of flower.

If I use neem oil, how much do I need to dilute this stuff? Do I need to use anything else? All suggestions are appreciated. Thanks!

is it on the buds? is in the nutes or the environment thats causing the mildew?

treat the cause not the symptoms

too humid not enough airflow increase airflow around the plants and drop the humidity.

I have a 12" oscillating fan on the grow. It isn't on the buds, just the leaves at this point. I'll probably have to look into buying a dehumidifier and covering my res better.

You never want to use just straight neem oil, you will end up screwing up your plants leaves badly.

i have a powdery mildew problem and i sprayed milk and water mixed on the mildew 2 weeks before harvest and it didnt do any harm and was quite effective

You take a huge risk when you spray that close into harvest, but sometimes you have no other choice

it was getting a bit bad stitch , so i just put the fans on full and hoped for the best .
and luckily it turned out ok , and without the sour milk smell i had expected

Well, there larve will still be on those leaves, you just knocked off most of the adults, they will come back, they don't get rid of that easily, they are like the plague that will live through nuclear meltdowns and shit.

Try using zero tolerance, by ed rosenthal. I think it sucks for big amounts of bugs. But when used in a very duladed form it still kills PM in a day or two. gone, zero, zip. All organic.

mildew is not a "bug" so neem oil will not deter "it"......as far as I understand Neem and bugs..........

Ecolizer Link Up is meant to deal with mildew, but works better pre emptively, as others have said, ventilation ...more extraction, but most importantly of all, movement, there is no way your plants have mildew if they have proper air movement.
