When these seedlings were transplanted outside last week, they recovered almost immediately (for 2-3 days, the weather was unseasonally very warm - in the low 80's) but then came the usual chilly weather (69-70) with daily showers and thunderstorms. The tomato starts are exhibiting P deficiency again: purplish stems, droopy leaves with tips curving down. What should I do?

If it were me I'd do nothing at all.
They'll snap out of it when they want to or feel like doing so when the weather warms up. Seriously.
