Mary-Anne, I'd be most suspicious of the 107 degree days and lack of water,
but were I you, I'd contact the county extension agent. There is a disease
called curly top virus that is generally intermountain in the U.S. (we have
it, and the chile-growing areas of New Mexico have it in spades this year).
I have learned that it does occur in Oakland, CA, and I think you're in the
east bay area...don't know whether it occurs in your area or not. It's
conveyed by an infected beet leafhopper that can ride the winds for up to
200 miles, according to UT research. They're transient, so there's no use
spraying. It's called curly top because that's one of the symptoms on
tomatoes (when a six-foot tomato plant gets it late in the season, you
grieve), but it also affects other solanaceae, beans, beets, squash, etc.,
and some flowers. 

No cure, only defense is prevention or plant curly top resistant plants.
AFAIK, the only resistant plants are tomatoes: RowPac, Saladmaster, Roza,
Payette, Columbia, Owyhee, and I think there's another, but I can't recall
the name and my seeds are in the basement (physical constraints prevent me
from going there). They're all red, smallish and from determinate plants.

I hope it's just drought-related crisping.  Margaret L
