Brown powdery dust on plant
A couple of buddies who shared clones noticed this weird stuff on their plants and I was curious what it was and if it was something to be concerned about.... thanks anyone who has a clue

Man that's crazy! Good thing I don't have any plants up and just seeds! Worse is I know one has seed stock. Thanks for the thread I'll read through it and pass the information along.
I know one of the guys has a flower room were all of the leaves suddenly looked like their curled up and died 4 weeks in flower or something. |

I can't help with any methods of combating them.
I shut down, killed everything and waited a month. Sprayed, bleached, fogged, Hot Shot pest strips brought in and luckily I have not seen them since. |

All I know about spider mites is the web's are a clear sign. You can also see their black bodies crawling around everywhere.... called the borg for a reason. Maybe I'll put some other pictures up from these infected plants tomorrow.

Russet mites are not visible to the naked eye until there are thousands forming what looks like a brown powder. When I saw the title of this post I knew the answer before even opening the thread. I thought it was a powder of some sort too when I had them. |
