That would definitely make it look like a clogged nozzle... pretty much does the same thing, not as much filament comes out as desired.

As far as the temp goes, I did see that on their website, and I also saw where they posted their product on multiple other websites that it was 220-250. Rule of thumb with PETG... Too cold and you will see the gaps, it won't melt smoothly between layers... Too hot and it will get super stringy when it retracts and leave spider webs everywhere. I found the best results when my fan shroud broke and I quit using my fan to cool... so 0 cooling.

As far as the bed temp goes, you should be good anyway in that range. The bed temp is just there to hold the print on the bed. I see you print in a box (same for me), and with PETG, inside a box I am able to run down to 75 degrees with no issues.

If you give those a shot, your lower screen shot of benchy will be even smoother.
