    What's happening to my leafs?

    Couple of different things happening here:

    Photos 1 -> 3 on cucumbers. Started off as brown tinges to edge of leaves, eventually leaf died. Removed others going this way, seems fine now - I even have about 5 cucs on a couple of my plants (they were sown back in Feb). All the cucs have now flowered - I took off the few when they started, but have missed some obviously... Have taken off any flowers now that don;'t have a lump behind them just incase (last time I had a REALLY bitter cucumber - hoping this time it'll be different). I've an inch long cucumber and about 4/5 smaller jobbies forming too. Exciting stuff - have sowed more though as I'm not holding out hope for these surviving. Not yet fed them.

    Photo 4 - Green sausage tom: couple leafs going almost papery like, dried out.

    Photo 5 - One of my aubergine plants has white spots on 4 out of it's 4 true leaves - another couple leafs are developing fine howerver.

    All plants are indoors, cucs and most toms on my kitchen window sil, others on other south-facing window sils in heated rooms (temp set to lowest rad setting above frost where poss).

    Thanks!

      This is off my tomato blog, looks similar to your first picture. maybe your pot is now to small to support the plant without watering problems.


      12. Q. What could cause the leaves of my tomatoes to turn brown along the edges?



      A. Leaf-burn or scorch generally indicates root injury, quite often caused by heavy amounts of fertilizer applied too near the roots. This injury often results in browning and die back of the ends and margins of the leaves. Other possible causes are root injury caused by nematodes, insects or physical injury by cultivation. Also overwatering or underwatering along with diseases might cause leaf-tip burn.

          your compost looks really wet: could you be over-watering?

            With toms, rightly or wrongly, mine have always got their feet in water & have been fine every year.

              I would go with over watering too.
              I think it depends on the type of compost you have to be honest. I'm having problems trying to find ones not peat based over here-they tend to stay soggy- and then are suddenly dry.
              Are you checking how damp the compost is before watering- the surface may be bone dry , but the roots are fine.
              The last piccie looks like sun scorch from water droplets left on the leaves.

                You can also get crispy leaves if you splash water on the leaf and it catches the sun through glass. The water acts like a lens and literally burns the leaf.

                  I had just watered them, left them in their saucers a bit too long whilst I put the baby to bed.. I'm only really watering them once a week (as advice taken from zazen).

                  Ah right, I used to water from the top with a spray gun so that does explain it.

                  Thanks all, I'll make sure my watering habbits are more controlled

                    On the second pic how many leaves look like that one? It looks a bit like magnesium deficiency to me. If it is some Epsom salts in the water should help.

                      the first 2 true leaves look like that Guttata, rest seem fine..

                      I'll check the roots tonight to see if they're getting pot bound or not too.

                        Could it be a bit of some sort of botrytis-like disease? Any furry bits on the leaves? Got to be a possibility for damp plants of that size on a window-sill.

                        If so, I'd cut the leaves off and I'd back the plants to win for a bit once they're outside in a greenhouse or good patio weather.

                            Ok, having a further look at your pictures, it is definitely a watering problem.
                            There are definite signs of scorch. That is because the plant has not been able to take up enough water because of a root problem. Your peat does look wet so it seems it is not under watering, even though once a week seems not frequent enough if it gets warm in the window.
                            It seems like you have maybe had the roots too damp at one time which has caused the problem, so the plants now can't take up enough water during the hotest part of the day.
                            The pots look too small now for the size of the plants.
                            You need to repot in peat not too wet and hopefully the plants will make more roots, also keep them away from really strong sunlight.
                            You should not really get leaf scorch from the leaves being too wet with sun on them at this time of the year, unless it has been very strong in the window.
                            The best way to see if plants need water is to lift up the pot, if it is very light, then obviously it is too dry, and vice versa if it feels too heavy.

                              Yup... makes sense. My mother in law almost drowned my plants when we were away on holiday I had to repot all of them, but the largest ones I didn't get around to.... which would really explain it.

                              Thank you.

                              Just looked underneath, and a couple roots are poking out - so I'll pot them onto larger pots tomorrow.
