Clones Rooting, Powdery/Downey Mildew?

Today would be day 11 rooting for the batch in question,
I found what appears to be PM in 4/6 total clones.

I increased light, and slightly lowered humidity,
are there any other precautions I can take?
I have lots more clones rooting and really need to dodge an outbreak.

Also, the clones I found the spots on, it's just one or two spots total,
I remember reading that when it is present on a leaf,
it's already thriving throughout the plant, is this true?


I could toss the clones I found it on,
but I have them in a ziploc for now in case there's a chance.

Thanks rollitup.

dip a clean cotton cloth in skim milk, and wipe it off.

Just got this shit and had to loose my prized mothers and am currently controlling it in flower room. Shit is a pain in the ass. I would say toss the ones you found it on right away and see if you can keep it off of others (spreading spores by contact) If you end up getting it on the others i would say do an Eagle 20 (potent shit) while they are in veg. rumor is it kills the PM ( Also heard it never dies) or at least will suppress through flowering as to not ruin bud do not use this once in flowering stage.
Ive been trimming leaves with it off (only slight spots, spend lots of time with my ladies, saw it quick) ASAP, increased air circulation with additional fans, and am using a 10 PH water foliar spray (to alk.) Gonna try the milk mix too but have heard to use unpasturized which will be a pain to find.

[h=3]About the Fungi[/h]Powdery mildews are host specific -- they cannot survive without the proper host plant. For example, the species Uncinula necator, which causes powdery mildew on grape and linden, does not attack lilac. Similarly, Microsphaea alni affects elm, catalpa, lilac and oak but not turfgrass.
Powdery mildews produce mycelium (fungal threads) that grow only on the surface of the plant. They never invade the tissues themselves. The fungi feed by sending haustoria, or root-like structures, into the epidermal (top) cells of the plant. The fungi overwinter on plant debris as cleistothecia or mycelium. In the spring, the cleistothecia produce spores that are moved to susceptible host tissue by splashing raindrops, wind or Insects.

Moving air, low humidity and the milk as suggested. The milk gives a pH it can't live in from what I've read.

there is no need to turn the light off for your clone full 24/7 light will work faster...i root in 8-10 days. mold isnt good could mean toxic soil. if your soil smells like a septic tank they arent rooting there dying..just a thought but id leave the light on all the time..

Please read more before you write on the subject.
Nobody is asking about rooting light hours,
and I'm cloning in rooters, not soil.

My big healthy plants with roots and immune systems are fine,
PM case was in my cloner.

Thanks anyways
