  • Tomato leaf problem to identify

    Hi forum. I have a problem with my tomatoes which I cannot identify.
    The plants have got to the producing flowers stage. They germinated and grew vigorously. All the plants of this variety have the same leaf damage. They are in a cold greenhouse
    The variety is Blue Bayou and had a really positive write up which induced me to buy.
    Any ideas please? My other varieties are all healthy.
    Thanks.

    Have you given a feed it could be a lack of nutrients? Is that happening on new growth or just the older leaves,older leaves help feed the newer leaves so the new growth has the most health & oldest leaves can look a bit deficient. I feed mine seaweed at the mo,about once a month but you never know what the compost nutrient is like for each of us so if they haven’t had feed in a while I’m thinking that’s it?

      Have they gone short on water at any point in the last couple of weeks (enough to wilt)? And how long ago did you plant them out in the greenhouse?
      It's hard to tell from just a single leaf, but that looks quite like either damage caused by severe wilting (if they go too long without water then the leaves can start to die, starting from the edges), or sun scorch (if you were originally growing them somewhere less bright than your greenhouse, then suddenly moving them into the bright greenhouse can be too bright for them, and they essentially get sunburn).

        Thanks for responding
        I have not started giving any feed yet - they are not in their final large pots - but I can easily give them some extra nutrients.
        I don't think they were short of water but I do remember being a bit careless with watering and some leaves got splashed and then we had a really hot day! I did initially put it down to heat scorch but the leaves got worse over a few days which made me think it must be
        ​​​​ something else - so maybe it is the watering at fault.
        They have been in the cold greenhouse for 2 weeks - indoors before that

          As it’s happened to all the plants of that variety & they’re growing vigorously,also happening on the leaf edges,seems like a feed will sort them,or plant them out Composts have some fertiliser but if they’ve been in the same pots for longer than a couple of months like our tomato plants have I always give a little feed.

            What does the rest of the plant look like? It's some kind of wilt but not sure what, is the rest of the plant healthy?

              Just my opinion..I dont think its wilt...

              And when your back stops aching,
              And your hands begin to harden.
              You will find yourself a partner,
              In the glory of the garden.

                If it's on all the plants of the same variety it could be something that came in the seed. The only thing I've found that looks remotely similar is bacyerial canker. Sorry that doesn't help you though...
