Hi I've just taken these older leaves off my tomato plant and they look like this, none of the other leaves on the plant look this way so I was curious what this is caused by? is it just natural death of the leaf as new ones appear?

possible causes could include water stress, heat stress maybes? + whatever anyone else thinks this is? I don't think it's nutrient related as the plant has only just started flowering and this is new compost, will be adding tomorite once its flowers are fertilised though :)

suggestions or ideas are appreciated as I know very little about ailments and what different things with plants mean 😅😅

also also sorry if this is the wrong place to ask this
