Hi. I'm not much of a gardener but a friend gave me a Mr. Sripey seedling a couple of months ago. Up until about 2 weeks ago I had a healthy, rapidly-growing beautiful plant. I noticed that the leaves were curling. Did a little research, and most of what I read told me this was fairly common and was likely just a reaction to chilly night weather (it was getting down to around 55 degrees). But things continued to go downhill, and now in addition to the leaf curl (or leaf roll?), some of the top leaves are getting brown and dying. I've attached some photos. The baby leaves on the bottom are relatively healthy-looking, but the ones in top that are sprouting from the longer vines are getting limp and brown. Any advice is appreciated!!
