Brown patches on tomato leaves

Hello! New here, and new in the gardening world. I have a tomato plant growing in a pot and I noticed brown patches on the lower / older leaves. Overtime they appeared on more leaves. I'd appreciate it if you could tell me if it's a disease or what I should do to save the little plant!

    Water on leaves then burnt by the sun try just getting water on the soil only.

    Thank you for your input, but could it be something else? I have been careful to pour the water close to the soil and make sure the leaves stay dry

    They might just be older leaves and getting frazzled.
    Where are they - a greenhouse or by a window or similar? It looks a very big pot, so is the plant big already?

    Small plant, big pot with 18-20 litres soil and it has been in my kitchen next to a south facing window. I moved it to the balcony for a few hours on a sunny day, but it's too cold for the plant to stay outside overnight where I live

    It's very overpotted then. You should only move them up a suitable size each time. It'll be struggling when you water it, as there will be far too much wet soil round small roots.
    It's obviously been brought on in very warm conditions to have fruits. I take it you aren't in the UK?

    I'm in Denmark. It already had flowers and 1 tiny fruit when I bought it, and the advice I got (not from the seller) was to move it to a pot with at least 30cm diameter. The rest of the fruits appeared in the last week or so, at a south facing window in my kitchen at approx 23 degrees Celsius. What can I do to save it now? I imagine repotting to something smaller is dangerous. Should I try to water it less and closer to the root?

    Do you know the variety or anything else about it?
    I'd say the pot's far too big, but it's probably best to leave it there now. I take it you have good drainage in the pot too?
    It's possibly getting too hot at the window. Make sure it has some ventilation during the day, and you may even need a bit of shading for it in excessive heat, if you don't have anywhere else for it. 
    Definitely don't over water, and always water in at the foot of the main stem, never overhead. If you haven't done so already, give it a small feed. Once the first truss of fruits are set, that's the time to feed  :)
    Try not to over water it though.
