Is this mold?

The link below is where I found the powder mildew remedy. It has all possible signs of powder mildew. It's a white fine powder and it stinks like cheese. It was on one plant in the same enclosure and now it's on this one. The other plant had died but I left it in the room hoping it would recover for a while. No such luck. It dried off and then died soon after. When I did the autopsy, the roots were dry and flimsy looking but still white so definitely no root rot that time. On that one I tried a variation of this remedy but without the oil and soap and I did it while the light was shining on it so that might have led to it drying out, and dying.

The hydro method is a bucket with an air pump with hydroton clay pebbles as the medium. I changed the solution too because it was about time and I just wanted to make sure everything is clean.

I just wish I knew what to do to get past week 2.

Baking Soda Spray for Powdery Mildew - Organic Powdery Mildew Control

Update: I found that the carbon air filter in my room had the ozone generating ionizer turned on by mistake. Could the ozone be the cause of this damage?

Caught this link from your link: GreenCure fungicide for curing and preventing powdery mildew, blights, molds and other plant diseases Did you check it out? Is that what it looks like?

Whatever it is. Sounds like your grow area is contaminated and you need to clean it all up. Use new soil. etc. . .

(perhaps the Chinese worker dropped more than rice?)

Also....be careful with how much of the spray formula that you spray on the little one in the dwc bucket.... If any of that should happen to seep down into the rez....well let's just say that you don't want ANY of that in your rez....

I've experienced powder mold....your RH has to be waaaaaaaaay higher than 50%.... Talking like constant wet and muggy conditions for PM.... You sure your RH is at 50%....

The ozone generating ionizer is not causing this.... Where does your exhaust go??? Recycled into the same area or does it go outside??? How much, how often does your grow space get fresh from outside air???

CGI::::::

The RH was around 40% and Temps 88 F around that time. Air goes outside of the enclosure, a small oscillating fan was blowing around slowly, window was open at the time so all air was from outside.

It looks like the powder mildew is gone this morning and even the smell of it has subsided. Does the plant look like it could recover? Last one didn't.

Sorry to be the one to say it....but....that lil one's been dead for at least 24hrs....

On your next go, don't try the "remedy".... And like already mentioned....clean and sterilize your grow space....

Where do you have your RH gauge monitoring???

Don't even use that hydroton again.. I hate that,My Friend! I just lost a plant I had in reveg. My fault! I hacked the rootball a bit much as well as waited too long to trim the rootball. So.. She's DEAD.

I feel ya pain!

Ga.

>On your next go, don't try the "remedy".... And like already mentioned....clean and sterilize your grow space....

It already looked like that when I found it with the white powder on it.

> Where do you have your RH gauge monitoring???

On the bucket.

It's strange that it happened before with the soil and now with the hydroton. Must have been in the environment. I wonder what I can do to sterilize everything without introducing nasty chemicals.

One more question. Could this be strain-related? Could this "auto-blueberrry" just be smoke-and-mirrors?
