PLEASE HELP!!! WHAT ARE THESE BUGS ON MY FABRIC PO...

That is 100% the start of an infestation of russet mites/spider mites . This comes from the lack of ventilation and wet mediums ( in your case soil and fabric pots) There's many many many different way's to treat this problem . Firstly I would get some neem oil ( really cost effective ) dilute it with water and spray everywhere ! I mean spray the pots the top of the soil the base of the plants the walls of your growing space . The reason i say this is cause you wanna get rid of these little intruders as well as get rid of any eggs they have left behind , the oil will coat them and they wont be able to breath ultimately resulting in their deaths . The secondary thing I would consider if I where you is having a fan blow air on your fabric pots this way it will facilitate the soil drying up aswell as the fabric pot (perfect combo for nesting grounds if left super moist for long periods) You can try all the internet methods and the rest but I've been gardening for years and the method I just described to you above has never failed me! I hope this helps you on your journey to become a Grow Master ! -Happy Growing!
