Neon Pothos – yellow leaf and black dots?

I’ve had my neon Pothos for 4 days, and I have some questions.

1. What‘s up with the yellow leaf?

2. What are those small black dots? They don’t feel raised at all.

Context:

I’ve repotted her in a pot that’s probably a bit larger than the recommended size (photo attached).

I repotted her a couple times in the past two days, actually. Once when I first bought her (from plastic to terracotta), another time when I dropped her pot and it shattered :’), and another when I briefly removed her to amend what I learned was hydrophobic soil.

So, Oopsie, her first few days in my care have been a little rough.

But now she‘s watered, her soil – to my understanding – is damp enough but not soaking wet. (I.e.: I don’t think dryness or root rot is a problem, but I don’t want to pull her out again and just stress her out some more if I don’t have to.)

I’ve got her in front of a west-facing window for now, while I’m out of town. But I’ll have her in an east-facing window when I get home in a few days. I’ve also got a grow light (idk what kind; I got it from a garage sale), about 10-12 inches above her. Because I have been reading that neon Pothos need a lot of light.

She has a couple new leaves (!!), so I don’t think I’m completely failing lol.

But I’m not sure if the two things I asked about are stress related from all the reporting or issues coming from the conditions I’m providing her.

TIA!!
