I agree man. that is 100% russet mites and they do suck bad. We had a Russet Mite breakout out here in one particular region and destroyed the whole valley's crops. No one knew what it was. It looks like a fungus with a furry brown/rust color especially on the fan leaves, you can see the haze on the top side of the leaves and follow the color along the viens till they meet at the base of the leafe stem. Everyone around here misdiagnosed it as Rust, and so I go out to that region and I pull out the microscope and BAM, billions of fuckers, so many that the leaves tinge brown/rust and they are so small it just looks like a dust or something. I will tell you that the only people who salvaged their gardens were the ones who used
Avid in conjunction with the eggicide stuff that kills eggs, and they all used those atomizer sprayers where you could mist and cover every square millimeter of the plant. Its hard from your pics for me to say for sure, could you take a pic of the rust/brown "soot" on the tops of the leaves and the conjunction point where the fingers of the leaves meet the base of the water leaf stem. I can already see the "burning/dying" off look of some of your bud sites which is also a very good sign of those fuckers.
