Looks more like ph issues or a deficiecy than light burn.

Looks like a calcium deficiency. Likely from a ph issue. What's the runoff testing at?

This is more than likely a little over watering (yellowing area on top) and a spike in PH (what may appear yellowy and brown in white light).
I wouldn't say calcium so soon, because I believe paying close attention to the PH will more than likely not continue with spotting.

Good call on the yellow. I didn't notice that. And I forgot that under that lighting it's hard to tell what color the spotting is. The drooping leaves would match a bit of over watering. Be nice to know what the growing medium is. With your comment, I would now say let it dry out a bit and see if new leaves show the spotting. If it's soil, collecting runoff could just exacerbate the problem.
