Today was able to lift the car and noticed some coolant at the plastic access door on the passenger side underneath the car, so I'm hoping it's not a major leak. The drain plug has some residue so I'm going to try and remove the front bumper sometime this weekend or next to check out what could be the culprit. I have 19k miles, 5k miles since the radiator was installed.
Update:
Determined that the drain plug was the source of the leak. I was able to tighten it about 1 full turn. While the drain plug was loose, my coolant temps read over obd2 were 205-215F. After tightening the drain plug, temps were back at 190F, which was normal. Coolant wasn't exceeding the 1.3bar radiator cap since it was escaping out the drain.

My robispec cooler is losing coolant. Every time after I have driven around for a while I notice coolant on the bottom plastic panel underneath the radiator. I have to constantly fill up the radiator itself (the overfill bottle is always empty). I had sealed that drain plug with sealant (Amazing Goop thread sealant) so I don't think it is leaking from there?
