Runtz muffin

Starting to see some buds though they r so small and it really is starting to get a smell on it now. Used some bti dunks through this week and I've got the weirdest problem. I don't even know what they are I'm struggling to find any information besides soil mites. And they r not in my soil they r on my pot. I'm thinking it's due to the cardboard box I had put in there to raise the fan and the moisture or it could be down to the coco. Research research research. Looking like I'm gonna run out of vertical space also so I'm gpn a have to botch up a way to raise the light to the ceiling hahah.
