On the heals of musa's posting "yellow leaves on paph gigantifolium" I have identified a similar condition on my PEOY (newly arrived plant). It's only on one side at this point. I've removed medium that was in contact with the leaf. Is there a chance it will dry up on its own? It looks like there was a similar condition on the next lower leaf which seems to have stabilized. Would treating with Physan 20 help, or maybe dabbing with peroxide? Attaching photo. Thanks so much.
