Nozzle Clog

Hey guys! I have Creality K2 and i am used to clogging on pretty much every filament change.. But i recently swapped to 0.2 nozzle and now when i switched filament and got clogged i had to remove extrudor and go with cleaning needle from the top and it worked.. I extruded once but filament started going to the side of the nozzle and stucking there.. I thought it was some old PLA left so i cleaned it with a brush and now it’s clogged agian…. I don’t know what to do.. 0.2 is to small to insert anything from below.. Do i have to take it apart again???
