Phosphorus deficiency is likely - those purple leaf edges are a classic symptom, especially when the plant is otherwise stressed from temperature swings or wet condtions, just add some bone meal or a balanced tomato fertilizer to the soil and water it in.
Potassium/ phosphorus deficiency?
Maybe! Elsewhere someone also said maybe water mold! And they’ve been wet lately with the rain!

I am planning on giving them more tomato yum yum fertilizer tomorrow, so if it’s that, then that’ll also help! Thank you!
