Wrinkly and yellow tolumnia leaves

[2SadDeadPhals]

Hi! Newbie here. My little tolumnia seedling has been growing a little new fan for the past couple months. I think it grew maybe 1mm. The other leaves have kind of turned yellow, and 1 leaf died. Another one in the middle is wrinkled. I have it in a mesh pot with medium bark and water it every other day or every 2 days. Checked the roots, they're all alive and growing. I've added a bit of sphag just to see if just needs more moisture in between watering. What do you think?

Thanks,

Phals
