Early sign of PM?

Definetely looks like it? RH? Get a dehumidifier or use more fans!

Rh is been @ 20-30max and hella wind

I was just looking through my journal and noticed that I foliar sprayed with AgSIL-16H on 2/7 could this be from the silica?

Should PM rub off? Because it doesn’t seem like this is rubbing off with a wet paper towel

No idea buddy hang in there and wait for more replies. Good luck!

It sure looks like PM.

You're going to have to hit it hard while your plant is still in veg. Potassium Bicarbonate, wet able sulfer, Dr Zyme's Eliminator, Sulfer vaporization, UVC light, are just a few ways you can attack your infestation.

Do you think this clone would have it as well taken on 1/25 kept separate?

Gonna spray it with neem tonight just in case. I got some flowering autos in the same tent so my question is if I spray the neem on the plant and put it back in the tent with the flowering autos, will the auto’s buds be fine? Or will they pick up that nasty smell from the neem plant?

Just sprayed the fuck out of it with Neem oil. Will it be OK to put back in the tent later tonight with the flowering autos?

Also, how much Neem oil is too much Neem oil? for example how long should I wait before doing another treatment with neem oil?

*Bump* is this neem spayed plant ok to be put back in the tent with flowering auto’s?

Have never dealt with PM, but do know it can spread. Keep it separate from the others if you can, and scrub down everything in your tent with disinfectant, spray down the plants in the tent with neem as well, I’d keep using it even if you get the PM under control. Just my two cents, other people around here could probably give you a better plan - good luck!

One of the best defense to PM is a healthy plant, see if you can remedy those yellow leafs.
Looks like N and Mg deficiency

It does look like it could be residue from the Si foliar spray, but it's hard to tell from pics. I do agree the plant looks underfed. Usually I see the first PM blooms as small circular areas initially.

Si is generally very high ph, which would create an undesirable host for PM as well.
