Hello again! Can anyone advise if the white marks on my tomatoes plant leafs are caused by being moved from indoors out into direct sunlight too quickly? If not what is causing this? 

Any help would be greatly appreciated :)


  • I’ve grown tomatoes for 30 years but this year I have the same problem with the leaves on the ones in the green house and really have no idea why?

    It's probably environmental and possibly as you say.
    If the new growth is looking good then it's probably of no concern.
    You could check on the back of the affected leaves just to make sure there are no bugs near the marks, ideally with a magnifier
    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    Possibly they felt the cold in the move. Or sunburn from wet leaves.

    Thank you for the responses, I've checked the leaves and cannot see any obvious pests causing the spots. I will keep an eye on the new growth and hopefully won't see the same with newer the leaf.

    I have had the same problem causing a lots of white on the leaves after putting the plants outside for the second time . I think its sunburn as when I've put the plants in partial shade for half the day they seem to do much better.  Glad it's not just mine that are doing this.

    Not pests - just as @Pete.8 and @purplerallim have described. Difficult conditions for now, when getting toms acclimatised  :)

  • Morning, I’ve had a good, but quite late crop of tomatoes this year, however a lot of them have split when just about ready to pick. Overwatering perhaps? Or over feeding? I’d be happy for some advice.

    Splitting is usually inconsistent watering, like if outside you can't stop it raining.😁 When it gets late in the season I slow the watering down, to only if the soil feels dry, or the leaves start to curl. I have been informed on here that stressing the plants in late season helps with ripening. As for feeding I stop that about the beginning of September , but others work slightly differently so may get other opinions. 
  • Thanks, good advice

    Some varieties are more prone to splitting too. Sungold is, for example. 
    Mine have definitely been a little more hit and miss this year, but the weather has had a hand in that for a different reason.
    Mine are undercover, so watering is down to me only, but the temps have been very low at the wrong times, which has made things harder.
    The watering regime should be consistent, but they should be left to get slightly on the drier side before watering again, if possible. They shouldn't be permanently wet. 

    If you pick a bit earlier, and ripen indoors, it helps a bit.
