Cr-10s v1 prints curling at edges

Hey printing noob here. I switched to creality glass bed and a bl touch running tiny machines 3D firmware. I have been getting curling at the edges of my prints. Printing sunlu pla green at 205 bed temp at 60. Initial brim prints normal and sticks the. About an hour into the print the edges start to curl. And the brim breaks loose. Is it an issue where my a offset isn’t low enough the initial filament laid down is rounded with not a lot of squish would that cause curling at the edges? Thanks in advance for the help.
