What’s this leaf up to? What am I doing wrong to the poor leaf?

The photo is a bit blurry, so it’s unclear what the white specks are. With limited information, it could possibly be
- Sun scalding (sun burns for plants)- shade cloth can be used to reduce sun exposure
- Insect infestation- check the back of the leaves and stems for unwanted pests
- Fungal infestation- humidity plus heat in late summer can cause fungal issues
The leaf to me looks green with purple edges! There have been no insects though, I’ve been checking for those quite a bit and seen none.
Three seems very likely. It’s been very veery very humid and wet and hot at points! Thank you!
Potassium/ phosphorus deficiency?
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.
I am planning on giving them more tomato yum yum fertilizer tomorrow, so if it’s that, then that’ll also help! Thank you!
Maybe! Elsewhere someone also said maybe water mold! And they’ve been wet lately with the rain!
How cold are your nights? Tomatoes produce anthocyanins when it gets cold.
It’s been getting to around 65F at night, but last few nights have been cooler but not by much! It’s generally been pretty hot here, up to the 90s with so much humidity.
Ah they’re usually fine till under 10c but I do also believe it will create anthocyanins under more or less any type of stress as well. Bugs, rain, wind, etc.
