Young Tomato leaves developed white/grey tiny marks in random trail formations.
Growing in a greenhouse. Do not recall seeing this before .

    Pictures please...some of mine have the same, was advised it could be Tomato Leaf Miner, but pictures will be a big help in establishing what it could be, after all it could be nothing to worry about.

    Hope this helps ?

    The white marks don't look like mine, mine were more little trails where yours are more round with dark central spots.

    This should bump it up the board, so maybe someone else can offer a suggestion.

    Hi @Quinces I've posted the image on another forum to see if anyone can help in the dedicated Tomato growing section, hopefully someone can and I'll report back when they do.

    It's not unusual for tomato foliage to get damage. Is the greenhouse well ventilated? If not, and it's hot and humid in there , they can get spider mite. I've never had it, so I don't know if that's the effect of it.
    The other thing is that they can get damage to foliage that's against the glass. The fluctuating temperatures, especially early in the season, can cause all sorts of damage. 
    If they were in the house and have recently gone out, that can have an affect. Greenhouses don't have the same insulation as houses, and it's harder to have a steadier temp in them.
    Mine won't be going out to the growhouse for another week. It's not consistently warm enough at night, and they aren't terribly big yet. 
    What do the rest of the plants look like? Are they still small plants? 
    It's a place where beautiful isn't enough of a word....

    It looks like thrip damage to me
    I've not had it on tomato leaves, but sometimes on herbs

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    Ah - that's the one @Pete.8.
    That's often down to humidity and poor airflow too, I think.  Would you say that Pete?
    Never had those either.

    I've only ever had it on herbs growing outside, especially oregano, marjoram and thyme. The worst damage seems to happen to those that are in full sun all day. The same herbs elsewhere in the garden that get less sun seem to be ok.
    The spots on my herbs were not so large.
    Maybe a giant thrip :)

    Not sure I'd want to see a giant thrip @Pete.8  :D
