Great first layer, terrible second layer

Hello all,

This issue has been plaguing me for a bit now and I cant find the issue. I've been trying to do this large almost bed sized print, and the first layer goes down perfectly, at least it looks like it to me. The issue comes with the second layer. It creates this super rough texture on the nearly perfect first layer and it snowballs from there. If I let in run, the third layer will scape the nozzle against the second as it continues and so on. I tried to see what the forums had to say, and the main post I found recommended turning off the fan for the second layer as well to see if the issue persists and it did. I did a bed level test from Thingiverse that turned out perfectly and did not present the same issues that this print had. I've run all the calibrations on the printer and messed with the Z-offset multiple times with no luck. The texture seems to get worse towards the middle of the bed, the corners and edges seem to get it less. Any help would be greatly appreciated.
