Thank you
@tarev! The entire stem is slightly softer than my other plants, but no overly soft spots.
I uprooted it yesterday to check for rot down the stem, or for root rot, and none seems obviously present. I was hesitant to disturb it since planting, but wanted to check for rot. I also mixed in more (plain) perlite to better aerate the soil. It's exposure now has part sun as you've suggested.
