Help! I bought 2 Plumeria cuttings from my local nursery in March (I live in WA state) and both were doing great and started producing leaves right away, however, one of the plant's leaves started curling about a month ago. I went back to the nursery and they suggested that I give it some food so I bought some Miracle Gro plant food thinking it would help and it hasn't done much.
I've attached 2 pics of the curling leaves and my other plant that's healthy - for now. Does anyone know what could be happening? It's been indoors by a bright window the whole time. Thanks for your help! I've never had Plumerias before so I'm not sure what to do.
