White things on the leafs

[ajicacap]

Hi all. Woke up this morning and found some white "things" on some of the leafs, don't know what's it. definitely not trichoms and they wasn't there yesterday.
Humidity correct so is not mold either. any know what is it?

Still in the right humidity you can get WPM - the spores can come from anything. Your clothes - from fx if you been outside and go in the tent right after. Pets- dogs and cats.
looks like WPN to me.
too stagnant air will get you mold - if you invite the spores inside mate

I agree with Captain it looks like WPM. Have a read about it.

What's the chance it hermed and is dropping pollen on the leaves. I've had that and stupid me years ago thought it was an ash, cause I ash in my pots. And it was pollen and I think I seeded the whole batch right there when I blew it into the air. Just a thought.

[CaptainWiese91]

Then you must show us pictures of the buds ?
But it certainly looks like WPM - even if you have the right humidity..If this was my plant - I would treat it right away to save the rest

[ajicacap]

Buds looking good just leaves have it.

[CaptainWiese91]

ajicacap correct. But spores you can’t see them with the naked eye. Who know maybe tomorrow more leaves or even buds have WPM because the spores is already in the grow room.

[ajicacap]

I agree with you. Tonight nothing can do about it. Just wipe leaves witch is effected. Tomorrow going to buy some treatments.

[ajicacap]

I agree with you all, it does look like WPN. However, there isn’t any of the stated things, like air ventilation, high humidity or air movement. So I don’t really understand how it happened unless someone brings it.
Thanks, I'll go tomorrow to buy right treatments and will get rid of it.

They even found WPM on the international space station in their grow room with salat and tomates.
It can be the smallest things that bring in the spores. I battled with it last winter. And I even still don’t now why I got it. Can be anything. I’m sad to give you this news. But just react quickly too it, and keep and eye out for the rest of the grow now🙏🏻 I sure hope you make it to harvest - I didn’t

[ajicacap]

CaptainWiese91 you can see on the leave WPN but bud looks ok. Today starts fifth week. Hope I will get rid of this easily.

[CaptainWiese91]

Yea. Deal with it quickly. Because I bet in a few days there are more leaves infected, you just can’t see it yet. Read the toturial in here. The spores can we every where.
I remember when I had it, I sprayed all the infected leaves, took of the WPM gently. Next day - new leaves with new WPN and só on, so on. Until you don’t have any more leaves to desinfect. Or you end up removing so many leaves to control the infestation. And in that flowering stage, it’s crucial. Because the plants isn’t making anymore new leaves.
Be careful when you clean the WPM off👍🏻

Hey ajicacap , while your treating your plants, be sure to treat/spray inside of tent and everything in it too.

[ajicacap]

homegrown thanks for letting me know!
Any way if I'll spray it all over it how my buds react to this? Now is starts fifth week

[homegrown]

sorry ajicacap, i take all my plants out of the tent when i treat the inside. You can mix up a water/bleach solution and wipe the inside of tent and poles, all fixtures,racks,etc. As far as spraying your plants...there is lots of products for WPM, but not many that i want to spray on buds! There is also some home remedies, such as milk/water spray, and a baking soda/cooking oil/soap concoction that i'v heard of.

"Trifecta Crop Control" is said to be safe to harvest, it is also pricey. I can say I used it last year and it left no noticeable taste. I also added fans to the outside plants and took all growth (leaf and bud site) within 18" of the ground.
Some use 8 parts water to 1 part milk, I tried it one time, I was afraid I would not be able to tell the dry milk from mold.
