I recently recieved two rooted cuttings of N. 'ventrata' and have noticed that one of them appears to have small white clusters on its leaves. I examined them under a 10x hand loop and they are wispy and dont appear to be insect eggs. Does this sound like mold and should I be concerned. Could this be the result of them being closed up for shipping? I have them outside so I dont think air circulation is a current problem.
Also as a side question the first leaf of the newly active node has died and turned black on the one without the white "mold" is this a bad sign?
