Temp tower with no real difference?
I just got a new filament (PrimaSelect PLA Chameleon), did some simple tests that looked good (at 205c) then printed this temp tower which didn't turn out very well and doesn't say so much too me so was hoping some more experienced person could help me a bit 
The marks on the back side, see on the top (colder) parts, what are those and did they show only due to the lower temp?
How about the stringing? I had retraction set to 0.5mm.
