I got this plant for my birthday (December2017) then not even a week ago (Friday 16) I took the plant out of its pot, put some drainage holes in the bottom of it, and put it in brand new soil, then watered it (must not of made the holes big enough, but I will) When I looked at it the next day, some leaves were yellow (I understand it doesnt just happen overnight....immediately.) I just looked at it again (Monday 19) and some of the leaves look like the photos... 'full' vine then a few inches above leaf it gets really thin/wilted... any ideas? what am I do wrong? thanks for you help (in advance)
