Hi. I am new to the forum and so happy to find this resource. I think I just made a rookie mistake by posting this new thread as a reply to someone else's post. I am sorry! Reposting here as new.

My ctenanthe burle-marxii (I believe) has a problem that is affecting the new growth. It appears to be a kind of scale or something that develops before the news leaves uncurl. Images attached. It has been healthy until now. I don't think it's spider mites. No sign of any insects and no webs at all. I would appreciate any advice. Thank you!

Welcome!

Its ok, we all face a steep learning curve when new to this site. Thumbs up

I do see what may be a scale in Photo#2 on one of the leaf ribs. Scale insects wipe off easily and may leave a mark but not a hole or tear.

I don't grow this particular plant but you may not be watering enough.

Thank you, Daisyl. So happy I found you all. Smiling I don't think it's a water issue. I try to keep it in the sweet spot, and I have a humidifier running during the cold winter months. Not sure what happened. It was growing like gangbusters, and now, suddenly, the new leaves are all weird like that. Whatever it is does not really "wipe off easily." It's kind of crusty and has damaged the leaf surface underneath it. Does anyone have any suggestions for treatment, something that can't hurt and might help? (Neem oil? Diatamaceous earth? Other?) Thank you!
