I think Ken has a good suggestion there. Also if you want to be extra cautious, you could treat it like a cutting and bag it up so humidity is very high.

It's odd that it should act that way. Are you talking about the leaf on the right of the picture? It looks like it is curved down a little. But besides that the whole plant looks fine to me. It looks like it's only that one leaf. Maybe you just monitor it and see.

You media looks great.

Just thinking here... Where did you get the coconut chips and was it washed and soaked in water before use? Perlite and NS s. moss should give no problems and is sterile. Just worried that the coconut chips may be contaminated.
