Last week I received a ctenanthes Setosa grey star in the mail from Etsy. It was looking great when I opened the package. All good until I repotted it in a larger pot (it was very root bound). I did repot it in a cold climate; was probably in the cold for about 10 to 15 minutes. Now there are these black spots on the plants leaves. There doesn't seem to be bugs or crispy leaves after I looked. Also these black spots have no texture and they don't feel bumpy. The leaves are not turning yellow though. This might be cold damage or something else, this has never happened before with any of my other plants either. The last photo is what all the leaves looked like when it arrived in the mail. I just wanted to know what was going on. Maybe you could help! :)

Hi. I am new to the forum and so happy to find this resource. 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!
