Philpatrick Posted September 3, 2019 Report Share Posted September 3, 2019 What type of lighting does this plant receive? What is the measured humidity in the plants growing environment? https://www.google.com/url?sa=t&source=web&rct=j&url=https://plantpathology.ca.uky.edu/files/ppfs-or-h-05.pdf&ved=2ahUKEwiXofPembDlAhW1Ln0KHWTTD0MQFjAHegQICRAB&usg=AOvVaw20KcWIT3EFgTShKlOdJJUY I have had plants with blister like growths on the leaves; not so much on the petioles like your plant is showing. A lab could test your plant to ensure it isn't a pathogen. Could it be a pathogen, the nature of the plant, or caused by adverse growing conditions? It could be oedema. You could quarantine the plant until a solid diagnosis is confirmed. Quote Link to comment Share on other sites More sharing options...
