Some of the information I've come across says that the cells in the tomato
plant that form the pigments do not function well in extended temperatures
above 83 degree F. They simply wont ripen. This may be false information, or
there are varieties breed as workarounds. Still you said temps were in the
80s...high 80s? Are most people having this problem in higher temp zones,
experiencing a heat wave, or just impatient?

My grape tomatoes have plenty of foliage, plenty of flowers and plenty

sun and temps in the 80's.

Do I just need to wait, or is this a sign of some deficiency?

Patience, Grasshopper. Around here we set out plants around May 1st
and expect (the first) ripe tomatoes by 4th of July. With a cool
spring, this may be over-hopeful. "...on the vine for (literally)
weeks" begs for factual data. My sister hasn't answered my last e-mail
in months. Well, weeks and weeks. Well, looking it up, 9 days.

Your tomatoes will ripen. Not to worry.
