The latest photos show the kind of damage that can happen when bleach is applied to foliage at too strong a concentration.
Agree that the medium looks very heavy and mucky and moving the plants ASAP is important. What is the granular yellow-green stuff on the surface of some of those pots? I can't get a good enough view at this resolution.

Gorbelly....Interesting message ...So I rule out the cat ...then the next paragraph really strikes home and I will tell you why ...I worked out the bleach concentration quite some time ago and thought I had it right IE about 45ml of 4.9% bleach to a litre of water ....I now believe this could be far too strong based on what I have now read in a recent post ...
My back up plants bought from a garden centre were (on advice) sprayed (because they are the worst for carrying disease so I was told ) and have been killed by the bleach and copper spray I carried out so things have just gone bad to worse...The granular stuff you see is a root additive that I was told to put round the stem of my dieing plants .... Trichoderma Granules name ROOTMATE Bio Fungicide.....as for my soil mix..I believed I was quite safe using commercially available Tomato Mix 2 parts with one part peat moss and one part perlite....
After two relatively good seasons of growing some tomatoes last year was a complete disaster which led me to joining Tomatoville ,,,I do not have anything like the diseases this season ...Maybe I over reacted to advice on my initial situation and made my situation far worse by using an incorrect bleach recipe ...I do not know ....
Maybe what I am doing now was the real answer...cutting leaves off with a pair of scissors as soon as they show the slightest sign of an infection...
