Is this powdery mildew??

Got these crushed lemonade cut 2 week ago everythings been fine potted em in party cups atm in just canna pro coco. For the last week ive added a humidifier just to up the rh a little but thats only been running 15 min every hr. Any way noticed today what can only be described as like when u drop ash on something. Seems to be on 90%of em . First thought was powdery mildew but nèver encountered it in my 7yrs of doing this. Any help appreciated

Aahhh shitt.... what do i do now ? No never seen the mum. Told the dude tho. My rooms so clean too.

First it usually starts with environment , more air movement and lower humidity then comes the eagle 20
I can't tell for sure if you have it

Ive took all the leaves with the white stuff off n took em out the room. Just going to have to go local shop n see what they got. Hopefully with em being so young n catching it early wont have no more problems. Got a sulphur vaporizer but means have to empty room n disconnect carbon filter ca it renders it useless if comes in contact with the sulphur and its a ball ache

I found this on the web it says you can use peroxide on light infestation https://www.questclimate.com/scourge-powdery-mildew-treat-occurred/

Just to say thanks guys. Opted for the 2 part milk 9 part water n tablespoon of bicarbonate soda. 2 days post treatment so far so good

I had to deal with PM once. In your case, good thing is that it happened early, bad thing is the spores are all over your grow area now. I've read that your milk solutions is effective but haven't tried it.

Neem on the plant (diluded per directions and with a drop of soap) works well and the plant seems to love it. Hydrogren Peroxide is the best and I would suggest that for everywhere else in your grow area. Some say it's ok on the plant too, but I would be careful using on directly on your medium if you are using organic nutes because it kills the good bacteria you need (I made that mistake with one plant when fighting the PM).

Also may want to back off with the humidifier (at least temporarily). The rH right at the surface of the leave (or any surface) is often very different than the room humidity, and the leave surface is the only place that matters to the PM.

Absolutely make sure you have some constant air flow over the plants, so those spores can't land and do their thing.
