Check out this great video of an active russet mite infestation. reference and a hat tip to hemp russet mites under microscope
These little suckers are very tiny and elusive . They will potentially destroy your crop if you’re not on it . You cannot see these mites with the naked eye and can be easily mistaken for a deficiency and can go undetected for months !! In result a drastic change in yield and quality if you don’t eradicate them.. This video was recorded with a 1000x microscope . Even with a 60x jewelers loop they are very hard to detect so beware ! All plants has been burned and my whole grow area bleached ! I also introduced predatorial mites , ladybugs and weekly IPM with Doctor zymes to my new inventory This the one I know off.
