Vines and Climbers: Help with my passion flower, 0 by LarryDavid

Here are some pictures of one of my passion flowers. It was doing great this spring, putting on a ton of new growth and becoming really full. A couple of weeks ago, I noticed that the very tips of the vines became crispy and stopped growing, then I noticed that the leaves that were being produced were kind of deformed (see the pictures). Can anyone help me figure out what is wrong? Could it be the heat--I have it next to my house on the west side (it gets pretty hot late in the afternoon there). Thank you in advance for your expert advice,

LD :)
