Hi,
I have done a bit of trouble shooting with my Ender 3 after getting strings like yours. First look at your temperature, try printing lower in increments of 5 degrees. I print PLA at 185.Look at retraction settings in your profile, increase the distance and speed (two separate boxes don’t get them confused!). Do this in increments until the stringing stops.
Other settings that could help:
Enable Coasting
Enable Combing
Here is a useful explainer:
