I am getting a little bit of incomplete lay down of the material - gaps etc on the first layer. I thought bed level but I am not sure.

I increased the extrusion multiplier from 90 to 95 and it helped a lot but it also made the subsequent final layers much "rougher" when compared to the same piece printed at 90 which prints really great. My thinking is I need to address only the first layer and not all layers. Does this make sense?
I print with 100% extrusion multiplier and 100% first layer height for all my prints. Most important part is to dial in your initial z-gap or z-offset for the first layer. This is all dependent on the thickness of your business card or piece of paper you used to level your bed. Plug that value in as a negative value for z-offset. In my case z-offset is set to -0.25mm (the thickness of the business card I used to level my bed).
