Super sweet 100s. Temps are low 45 high 75, get plenty of water. I read it could be the cold temperature, p deficiency, or TPLD disease? What do y’all think?

The phosphorus deficiency is usually (but not always) a lack of uptake due to cold and/or soggy soil, even though there’s plenty of available P.
Sounds like you’ve been researching it & are on the right track.
Personally, I keep my seedlings (in pint cups) outside even when the night temps are down into the mid-40s; yes, some will get some purpling (it varies by variety — and notably, cherries often do it the worst) but nowhere near as bad as what’s shown in your pics in the temps you described.
Unless that soil is *sopping* wet, I think you’d be wise to give them a basic fert just in case. A *soluble* basic fert, with a decent amount of phoshorus in it (I personally like miracle gro for that sort of thing, but there’s plenty of options). It won’t hurt anything, and you’d may as well hedge your bets.
It does go away with no long term harm to the plants once the soil gets warmer/drier (or if it is an actual lack of P in the soil, once you start fertilizing) if it hasn’t been going on *too* long…although some of those lower leaves are gonna be past the point of recovery.
