I Have PETG Problems

So I have had my Snapmake for a few months now. I love it. It works well with PLA but with PETG It leaves strings between areas when it moves and leaves lumps everywhere. The print itself is fairly good otherwise.
Could it be the filiment retraction isn’t right?
I would appreciate any feedback on this.

I haven’t worked with PETG personally, but there are several posts on the forum about it needing additional cooling. Particularly with respect to bridging and stringing.

If you can share some pictures and your current settings, more knowledgable users can give better advice.
