  • Is this the start of blight?

    As title really.

    Looks like it, but I'm not 100% sure....when my toms get blight the stems also are affected.
    If it is blight, I'm presuming those are the first signs???

    If you have any other piccies, that'd be helpful.

    Blight on the toms tends to look more brown/ wrinkley and in patches...you piccie is hard to see.
    If that black is at the base of the tomato it looks more like blossom end rot.

        I don't panic until I see dark brown/black patches on leaves and stems with a slight white furry coating. The patches on leaves often have rings evident.
        The proof of the growing is in the eating.
        Leave Rotten Fruit.
        Nitrogen, Phosphorus, Potasium - potash.

          How many plants look like this? If it's not many I would cut off the affected leaf sprays and keep an eye on it. Like Nicos says the tom looks more like blossom end rot and the leaf could be any sort of damage if it's just on that one.

          Check out the sticky http://www.growfruitandveg.co.uk/gra...ght_33866.html to help you decide for yourself.

              I don't think that is blight. The foliage looks too green and healthy. The tomatoes at my friend's house have blight and their leaves have the charactaristic brown blotches with a paler rim, mucky looking black splodges on the stems and a translucent brown hue on some of the fruit. I agree that tomato probably has blossom end rot.

                This is the first plant I've seen with this so if it is blight it is the very early stages.

                    Well I've cut out a lot of what looked dodgy and there's more air getting round the plants now so I suppose I'll just have to wait and see.

                    There's only one red tom, all the rest are green so I was really hoping the plants would hang on in there.

                      My greenhouse toms have had those symptoms for a month or more and blight hasn't developed. So you could be okay.

                        the bottom of those 3 pictures shows a leaf with the classic symptoms of magnesium deficiency. This usually affects the older (bottom) leaves first. Give the plants a feed of something like tomorite and they should be fine. Definitely NOT blight.

                          They've been getting fed Tomorite twice a week for a while now. I even measure the right amounts, I don't guess.

                          Those leaves were taken from the top of the plant, they weren't old ones.

                          Most of the 'bad' leaves were from the back of the plant so I'm assuming there wasn't good airflow.


                          Edit: Should I spray them with Epsom Salts?

                            It is not blight. It's magnesium deficiency. My tomato plant has it.

                              Like I say, plants have been fed twice a week so what to do? Increase strength? Feed 3, or 4 times a week? I don't understand why they are deficient when they've been getting fed at least the recommended amount. I did read somewhere that people feed every single watering but with a more dilute mixture. Maybe I'd be better trying that?

                              Mind you I'm happy if it is just a deficiency, I just can't get my head round why.
