Growth in Neofinetia possibly infected?

Do not allow leaves to sit in a puddle of water. This will cause them to rot. To avoid this, use plastic toothpicks or segments of drinking straws to elevate. Perhaps you can use the receptacle rim for this.

As far as the sphag, I recommend a 1/4” layer under the base and just some pieces of sphag sprinkled on top with 65% visibility of roots below.
