Danielle, the first one - with all the necrotic tissue - doesn't look fungal. It's something cultural. As Dov says, knock off the fertiliser and cut back on watering too.
The second one could be more problematic. Have a very close look. Can you see little blisters/pustules at the centre of the marks?
In the first photo, are the leaves on that plant quite thin and 'papery'? My plants got like that on the lower branches because of being kept inside for a bit too long (they weren't getting enough light but because of the cold at the time I didn't want to plant them out.)
With advice from italophile - as usual - I buried them deep into their final 25 litre pots, cutting off the lower branches. I did leave a few of the thin papery leaved branches as I didn't want to take off too much growth and they're still there now the plants are outside but they do in parts look like your first photo - the wind has whipped through the leaves and worn them down.
I'm not worried as all of the new growth coming through is a brilliant green (as opposed to the yelllowy lower branches, and eventually I'll cut those off anyway
Looking at the size pot, the plant with the purple marks on it's leaf, probably could do with a bigger pot. When I don't pot on tomato plants quickly enough or they get a chilled on a night....some varieties show these classic symptoms. But they soon disappear when put into their final 25lt tubs and continue to grow into strong plants.

They look just fine to me, different varieties show differing leaf development, colours and habits, and a bit of scorch here and there isn't life threatening. I've had leaves that look this way and never had blight. Been a tough year up to now for tomatoes. Take heed of italophile, I'd class him / her as a tomato guru. Not saying other members aren't wise, but I thought I know all there was to know about tomato growing until I read I's wise words.
Not a guru, KEF, I've just grown toms for 20+ years and, particularly in the early days, had the benefit of a lot of advice from some real gurus, particularly a couple of American tom growers who were incredibly generous not only with advice but gifts of very-hard-to-come-by heirloom seeds. Tom growers are a bit of a community - world-wide - and the more help and advice shared around, the better.
The best thing I learned about growing toms was Keep It Simple. Don't fuss over them, don't pamper, don't overwater, don't overfertilise, let them do the work. It's what their genes are programmed to do.

Seriously, these plants are fine.
Thank you so much for your help all! I shall cut off the affected leaves and repot and also leave off the fertiliser for a while.
Italophile - I can't see any blisters on top of the brown spots - they all seem the same solid colour??
Okay, Danielle, I thought I could see some amongst the patches. That's a computer monitor for you! Just out of interest, what varieties are they?
danielle, are those splodges a purplish colour? are the backs of the leaves at all purple or the stem?

Oh, and I'm a him.
For all those interested in toms, here a link I've found very useful, don't want to usurp your knowledge though, Italophile
