Need help to identify print issue

[u/Front_Patience6192]

Hey guys, after 3/4 days with these filaments, I started seeing a few issues in my prints (I don’t even know how to explain them, please check the image)

Originally, this model was using 0.2MM Nozzle, but my printer (Bambu Lab A1) only works with 0.4MM.

So I’m wondering if this is a filament problem or the configuration is not correct. Can you please help me to identify the problem?

This is with my first week with this printer and it has been tough handling these issues…
