My N. Ampullaria leaves are showing brown/red spots which seem to expand over time - see pics below (top and bottom of leaves). Whatever caused these spots didn't halt growth of the pitcher on the largest leaf. Now the newest leaf is showing some spots as well (easier to see at the bottom of the leaf which is on the right).
The plant is approximately 30cm from the lights, and none of the other neps next to it show any similar signs.
What do you think? Is this something I should worry about? Could it be some kind of pest?
