they are almost as small as spider mites but i would have to say a little bigger and crawl pretty fast for their size. they look whiteish and were hundreds on top of the soil of one plant that i know of pretty much only on the soil and rim of the pot. plant looks fine from what i can see and im a month into flower. please let me know asap if u have any idea i did a quick research but saw nothing that describes what i have + rep given thanks
