I purchased this Catyclia Atrowalker in Hawaii and one of four were open already. The next opened a couple days after arrival. The last two puffed out but were stuck at the tips so I manually took the tips apart (gently). They seem to be stuck at half open for the last 4 days or so. I am in zone 8b and we had some days in the mid to upper 70s last week. It's under some CFL bulbs also. Any ideas why this happened? Tips?
