    It could be scorch marks if the water splashed onto the leaves and then hot sun shone onto them, or I've found some plant feeds in water mark the leaves if it splashes them. Do you have a photo?

    Yes, it sounds to me like scorch - try to keep the water off the leaves when watering - damp leaves are very susceptible to blight and other nasty conditions.

    No-one knows if you've done your housework, but everyone knows if you've done your gardening !

    Hard to know without seeing a photo, Nicholas. You'd need decently hot direct sun to scorch leaves. Dove is right, though. Never wet the foliage, particularly in a closed environment like a cloche. The humidity inside will lead to fungal problems.

    I always try to water right down at roots which seems to be the answer Nicholas image

    It is the answer, Fairygirl. And, as the plants grow to their full size, take off the lower branches and foliage to keep a gap of 12-18" between the soil and the lowest foliage. Fungal spores can and will fall down onto the soil beneath the plant. The gap helps guard against splashing the spores back up onto the plant during watering.

  • ok all ill try and get a photo upto night

  • Hi folks this is the thing I'm talking about, hope the pic comes out ok.

    Pity the photo's not a bit bigger, but I can see little "bullseye" spots inside those necrotic patches particularly towards the bottom end of the leaf. Usually an indicator of a fungal problem, possibly Early Blight.

    I'd get them out from under the cloche and get some fresh air circulating.

     Took this pic of one of mine the other day. First time I've grown from seed so pleased with how they came on.

    Outstanding, Fairygirl. Congratulations. Which variety is it? When will you be planting it out?
