Dwarf Tomato Issues

Hi.
First of all I need to let you know that I know nothing about gardening/growing. I'm giving it a go though :)
I live in an apartment with 2 South facing windows so all my growing is indoors on a windowsill.
I have been trying to grow some dwarf tomato plants from seed on one of my windows for a few weeks now. There are 5 plants in a 20 inch long tray that is about 6 inches deep. Initially things looked good but recently things have taken a turn for the worse.
Firstly the leaves at the base of the plant shrivelled and died. I thought at first that this may be as they are no longer needed?

A few day's later I noticed some brown spots of dried leaf on one of the plants. The others still looked healthy so I ignored it. Was this my mistake?

This morning it's not looking good for them. Every plant has started to shrivel and I am absolutely gutted :(

I have been watering them daily with quite a lot of water. Could this be the issue? I have been adding plant food to the water too. I also have sprayed the leaves with the plant food infused water too. I'm beginning to think that wasn't a good idea?
My Chilli plant seems to be doing ok though. I planted 3 in this pot but 2 germinated and died. The remaining plant seems to be doing ok though.

Strawberries are taking an age and seem very hit and miss also.

Any advice would be very much appreciated.
Cheers

Oh, my. You are killing them with kindness. Too much water, and too much fertilizer.
"Plant food" is a misnomer. Better you should think of them as "plant vitamins and minerals." That it, something that is neccessary, but in small quantities. Plants make their own "food" from air and sunlight (and water).
You might also want to consider potting the tomatoes up into an even larger container eventually. Even "dwarf" tomatoes like a bit more room for their roots than that container would provide.

I assume you are in the northern hemisphere, how many hours per day of sun will they get? If none or only an hour or two your success is going to be very limited. Fruiting plants should get full sun (all day) ideally.

They don't look that bad.

I've seen better but it isn't the end of the world.

Slow down. They need even watering but do not want to be constantly wet or waterlogged. Don't over do the fertiliser either, you can quickly kill them with too much.
