It's a little hard to tell from your photos but it looks like your nozzle might be too close to the bed. The first layer looks thin in places and the baconing could be from the plastic being squeezed out the sides

Yeah, it can be useful to run a large 1st layer print (usually a test print) and live adjust the z axis as it's pouring the icing to get the best lines.
Over extrusion and first layer to close to bed.
Adjust z oddest 0.05mm and see if it still happens. You might also calibrate your e steps if you still see issues.
