See.... Im with you on this one, but I've been using the same exact Nutrient mixture for over a year now. The only thing I changed was that I added Dutch Master's Zone, to get rid of unwanted bacteria in the growing medium. But I've also added it to my hydro system thats in a different location and that plants are doing great.

So in all, I'm left to believe that its something airborne. It could be the temperature, but thats the only other possibility. But even with that, the temps weren't that far off to begin with.

Also keep in mind that these plants have been vegging for about 3 months now and have been transferred between 3 different locations. We cant flip the lights to flower or even bring anymore plants into the grow area until we have this issue under control. Sucks.

So I've been growing for many years, and have dealt with just about everything, from pest, to mildew/molds, lockouts, root rot.... you name it. But I've never came up against the issue of Rust Fungus. I just recently got it and its spreading like wild fire. I know that cold, wet conditions are ideal for Rust Fungus, so we plan to raise the temps, and apply some different Fungicides (since our current one obviously isnt working). The RH is already supper low in the room, so moisture isnt the Rating: 5
