TAZ6 - PETG first layer issue

Not sure if this is a Z-offset issue or a bed level issue, or a bed flatness issue. I’m attempting to print a large spiral and the first layer appears quite good except in two areas. The upper right portion of the bed has a slight issue and the lower left is terrible where the filament is either not adhering properly or something else.

The bed was cleaned with iso-alcohol and a thin coat of glue stick applied. Nozzle temp is 235c and bed temp is 80c. First pic is upper right, 2nd pic lower left.
Any thoughts?

Thanks, Mike
