My Confetti Syngonium has one really thick stem with aerial roots and at the top these leaves are clustered. They have been in this same stage of "opening" since I brought it home about a month ago and some even have damage on them. I dont see any signs of pests and all my plants have recently or are currently being treated for fungus gnats and thrips. Any idea what could be causing this? Should I chop it off? It seems this specific plant is having trouble opening any new leaf so what can I do to help it out?
