Having issues with PETG. Is this bed leveling issue, bed dirty issue, wet filament issue, or something else?

Increase bed temp 5 degrees, lower z offset by a few hundreths, and throw a trash bag over the printer to create a makeshift enclosure.
The z offset will likely have the biggest impact. Textured beds need to have their offset lowered to squish the plastic into the texture a bit more. The auto offset tends to detect the top of the texture as if it were a smooth plate. Your print is also showing some distinct separation lines on the first layer. For my Ender 3, I usually started by lowering my z offset by -0.07 mm.
Bed temp increase will help adhesion. Trash bag will help with curling, which PETG loves to do.
