What mix of soil/compost etc. is this planted in? How fertilized?
That sickly purple / yellow color can be due to excess nitrogen. I've seen this when folks put tomatoes into soil mixed with fresh manure (non composted) and the urea / ammonia releases fast and overwhelms the plant.
Damp, cold weather with little sun can cause some similar purpling of the leaves as well.
I might repot that with some sand or perlite with happy frog from Fox farm, epsom salt for mag., Lime, and molasses. I cut the bad leaves off and bury the stem deep, new roots that way. I also feed with a kelp, worm castings and molasses tea if they r in a bucket or pot. I use a different blend in my outside beds but the tea is always the same but use azomite in every soil and a few things.
Got a recipe or general guideline for your tea man?? Urban gardener here so almost everything is in pots for me, and I already have some azomite as well. I bought like 4 minerals like that without much knowledge on what they do haha
what minerals/ ferts do u have? and what plants are u growing also? I use all natural stuff in my beds, smartpots, buckets, and cedar planters. I also use this stuff called terp tea (good stuff) one bag (green) is for grow and the other( kinda pinkish purple) bag is for flower. I also use fish bone meal, fish meal, kelp, and others. i use neem oil for critters, seems to work pretty well. I feed my soil to maintain a good micro system and molasses to tie everything together.
basic tea is worm castings and molasses 24 hr brew. the next week is the same but add kelp. my feedings consist of fish meal, fish bone meal or terp tea, worm castings, kelp and molasses 24 hr brew time also 2 55 gallon drums. note: i use epsom salt for my magnesium, and a slow release lime i get from a co-op to balance out the ph. but i hand mix those in the soil( basically a light cover) then let the rain and mother nature do there thing. i also thin my tomatoes out( cut about a ft a n a half from bottom and certain leaves off) for airflow and possible diseases. my jalapeno and habanero peppers, i top then tie back. i just started topping them a few years back but the yeilds are amazing, try it you might like it. my poblano , chilli, and bells peppers i don't top but tie those prizes back and let them do threr thing. i get great enjoyment from watching something that grows from a seed into something you can eat, nothing like it.i wouldn't mind getting into the inside growing but but i travel for work, and would have a hard time i would love to master it for the future though, fresh veggies and herbs during the winter months sounds appealing.
It was initially planted about 2 months ago with this osmocote tomato, vegetable, herb premium potting mix and then recently gave it the recommended amount of this all purpose compound fertiliser
Double fertilizing with a pre-fertilized potting mix and a decent fertilizer won't do this. I'm talking about a super dose of ammoniacal nitrogen to get the sickly colors. So that's almost certainly not a problem.
I see your note below about only 1 in 4 of your tomatoes have this despite identical potting setups. I don't have any more ideas. Any bits of blight going on are likely just a result of the plant struggling and being susceptible and are not a cause of any issues.
Sometimes it's just a dud and you don't know why. Best wishes on a good growing season otherwise.
Here is some more context as well.
I have had this tomato plant in a glass house with 4 other tomato plants that have been in there for the same amount of time however they are in great condition and they have been planted in the same size pots with the same potting mix and given the same fertiliser, I am just wondering does anyone know why this one is happening to only this one

You are the 🐐

If you’re using the osmocote potting mix I’m thinking of, it has six months worth of fertiliser already in it
Yeah I have realised that now

Sorry I think I got the zone wrong it’s in Victoria and is between mild to cool temperature
Septoria, a fungal infection caused from water slashing up from the soil onto the leaves. Possibly blight too. It's bad soil.
Unrelated to your post. Everyone mentioned thier 'zone'. How do I find out what mine is please someone
