Consistent yellowing and curling up of tomato leaves

Hi folks,

Iv posted before on this topic but here i am again. Apologies. Judt hoping to get a better understanding of what the problem is here. The leaves have getting yellow blotches and curling up. After a few days the yellow blotches turn to brown patches on the underside of the leave.

The only thing is seems to be is maybe leaf mould from poor ventilation. Can anything be done about this other than increasing the ventilation ? Can i spray any sort of fungicide ?

I have cut off a few of the bottom leaves aswell to try anf increase vemtilation and circulation.

Please and thanks just want to know whats causing this!

    Maybe the dreaded photo uploading glitch has returned Jamie
    I'll try and post one below as a test-

    Maybe use a photo-hosting site and link to that?

    hi folks, apologies, didn't realise the upload feature was experiencing issues. Hopefully that link works, would really appreciate some advice on the problem. Grown the plants from seed and put a lot of effort into them so getting concerned about the issue!

    thanks as always

    Are you feeding them yet Jamie?

    If so what with?

    It may be a potassium deficiency, but no need to panic

    I have 8 plants and have been feeding 6 of them with comfrey tea and 2 with tomorite. But i have obly rrally fed them once in over 2 weeks. The weather has been pretty dull hear recently and i haven't had to water much at all. Or so i think anyway! Maybe im not watering enough ? 

    Thanks again

    A pic of the overall plants would help Jamie.
    Tomato plants get all sorts of leaf damage over the season for various reasons and if overall the plant looks fine and it's just a few lower leaves affected, I'd say carry on as you are.

    But I'm guessing by now you'll have some tiny tomatoes beginning to form?
    We don't know what's in your comfrey tea, so to be on the safe side and ensure you plants are getting the right amount of potassium, maybe just use the tomorite (20ml per gallon [4.5L] of water) for a while as we know that it is high in potassium and give them a feed every 7-10 days giving each plant about 1/2 gallon of feed

    okay pete thanks a lot. I will get a pic the whole plant and you can hopefully get a btter idea from that. they look ok. but the ones outside look a lot better. the ones outside are slower to flower and produce fruit but they look a lot more lush and fresh. but they are getting plenty of rain. Maybe i am not watering enough either, so they cant access the potassium maybe ? at one point when the weather was dull I didnt water for about 2 weeks. I kept looking for the leaves to wilt and they wouldnt, assumed it was okay and that when they started to wilt theyd need watered but maybe that not a great idea ? yep they have fruit on them now.

    thanks again,

    Can't see any problems there Jamie - they look fine.
    We can't provide perfect conditions for toms here in the uk, so there will be little bits of leaf damage during the season. A couple of weeks ago it was quite chilly, yesterday the temp in my g/h with the blinds down and all doors/windows wide open was 49c!

    The only thing I would note is you're tying the plants to canes which is fine, but I have found that the weight of toms when they're all swelling and getting heavier at the top of the plant can cause the whole plant to slide down the cane and sometimes snap the main stem - which is not good. I now use cord attached to the eaves with a breaking strain of 100Kg - just to be on the safe side

    Wont be long now and we'll both have more toms than we know what to do with :)
