PM DM or what

[mike4c4]

I have a blue OG that when my lights turned on i found 3 leaves that had what i thought was PM. So i turned off the fans, removed the plant, and removed the leaves and put them in a zip-lock bag. I left the bag to go get my scope and get a better look but when i got back there's no white on the leaves. thats why on pic. I dont spray anything ever on my plants. temps 75-79 humidity 33% 2nd wk of flower. The OG was a clone i picked up about 35 days ago.
I have never had or seen PM first hand so not sure if it would disappear if carefully put in a bag. And no discoloration under the leaves.

Powdery mildew

And do you have any pics?

One powdery mildew organic remedy is to use dilute solutions of hydrogen peroxide (9 parts water to 1 part hydrogen peroxide). Spray it on the plants thoroughly about once a week lights off.
I know people use Sulfur Burners, not sure on how long or what, just read it somewhere.

I have spray to get rid of it just trying to find out if thats what it is.

Well is it relative to your area? If so, do you see it anywhere around your the outside of your house, or a way it could enter your room? Also, can you further describe what it looked like on the leaves. Was it circular? could it be dust or drywall?

It was on 3 leaves first leaf it was circular and in middle of leaf. 2nd was was on the edge of a small piece of the leaf. 3rd leaf i dont remember but it was small, i smoked since then LOL. What i dont understand is after placed in a zip-lock bag laying on a table for less than 1min nothing can be seen.

well the change in humidity since you snipped the leaves, as well as the transferring motion could make the temporarily translucent. I have noticed when spraying for PM it looks like its gone when wet or higher humidity.

Ok time to break out the spray bottle.

Ok time to break out the spray bottle.

remember to spray right before lights out!

If you have what looks like mildew on leaves, you should improve your airflow by quite a bit. This costs money, but it might be necessary in order reduce humidity.

dont let humidity fluctuate. Its not so much high humidity. Its the fluctuation that causes pm and lack of air flow

quick fix foliars

1. diluted lemon juice in water

2. Very diluted neem oil in water

3. Neem meal tea

4. Aloe Vera diluted in water

5. Compost / worm tea foliar (long term )

6. Find a plant of any kind that is resistant to pm. Take that plant (roots and all) brew a botanical tea. Strain and use in a foliar and water with.
that plant will have a bacteria that deters pm. After water / spraying that tea a few times. Your plant will now have that bacteria.

best foliar that covers everything is natural mistik from dragonfly earth medicine

 

[stinkyjoe]

the only reason you have pm is not enough air flow.

there's black and white mould all the time in the air, if the air flow stops the mould settles...... Simple.

its actually harmless white mould and its the stuff you get on pepperoni sausage..... They let it settle on purpose for some reason i don't know .

all it takes is air flow to stop it settling .

 

[reddan1981]

prob salt residue where a bit of nutes have landed on leaves do you hand feed? If so obviously keep an eye out for pm but... I recon your alrighty. Again spraying on top of leaves will do the same, especially under hid.

PM is a bitch on steroids! Anyone that says its harmless, or simple is full of what the horse leaves behind! I've been using peroxide, vinegar, baking soda... read goddam nearly everything written about it and still am fighting it off! But, with a strict regiment, it hasn't gotten any further than the leaves(no bud or stem involvement) What I've found is what ever treatment you use, it will work fine for a short period of time, but it will develop a resistance to it, so you have to keep switching your plan of attack! Lately, I switch from 1 cup peroxide/ 1 gallon of water, sprayed one day, then with 8-9 tsp organic apple cider vinegar/ 1 gallon of water sprayed the next! It still rears it's ugly head again after 18-20 hours, so thus the switching up treatments! I am looking for "uncoated" aspirin, but that's not as easy a find as it sounds! I plan to add the 8 aspirin(uncoated) in 1 gallon of water treatment to the regiment. There are a few more that sound promising and I'll be experimenting with them!
Good luck!
