For me it looks like this:
1. You may print too few top layers.
2. The flow of material is constantly too low, because the lines are not connected to each other ... Check if it is already like this before the top layers.
3. The printing temperature may be too low.
4. There may be problems with a contaminated material feeder and or hot end and nozzle.
5. Generally problematic material is used.
Thanks for the reply! I usually use 4-5 top layers which is plenty and worked when I originally started using the printer.
I changed print cores to a new one to address that angle.
I've had the same result with 3 brands of PLA.
Printed between 200C and 220C.

This is underextrusion. Most often caused by printing too much volume of plastic in too short of a time. What is your:
layer height
nozzle diameter
line width (all of them)
print speed (all printing speeds)
printing temperature (all of them)
And is your filament PLA?
For example you can print about 5 cubic mm/sec of PLA through a 0.4mm nozzle at 230C but not at 210C. To get cubic mm/sec multiple 3 things: line width, print speed, layer height. Same formula as volume of a box.
