Tomato leaf problem

Can anyone give me some idea of what's going wrong with my Sweet Millions tomato plants? I've got three growing in my greenhouse and they all look a bit weedy and brown shriveled leafy (don't know the technical term). I've also got some Rosellas which all look a lot healthier despite both having exactly the same life experience (sown, pricked out, hardened off, potted on, watered, fed etc). In the first pic the Sweet Millions is the one on the right. I'm getting a bit concerned I'm doing something fundamentally wrong.

    🤔 that doesn’t look very happy. 

    Could it’s leaves have been wetted during watering? It’s important to just water the compost and keep the leaves dry. 
    If the leaves are wet and there is strong sunshine through the glass the leaves can be burnt as the glass and water act like lenses and burn the leaves. 

    There are several methods of shading plants in a greenhouse to prevent this if that’s what happened.

    Looks as if something or someone is lurking in the depths of your pot.  Difficult to say really.  Some plants just don't like the potting mix, position and others right next to it, thrive.  That's gardening for you!!
    A good hoeing is worth two waterings.

    Dove From Above - I've been really careful to only water the base of the plants and not the leaves.
    Tuikowhai34 - it just seems so weird that it's only the Sweet Millions that are affected. The Rosellas look fine, in fact I spotted the first two tiny little toms yesterday (that's potentially a light sandwich to look forward to), and the Gardener's Delights look ok, just not as vigorous as the Rosellas. Why does everything have to be so random??!!

    Clip off that sucker on the right and put it in a jar of water to root.. even if the main plant is a loss (and assuming it's not a disease), then that clipping can be potted up once it grows some new roots.  It will have the maturity of the original plant, so quicker to flower and fruit than a same-size seed grown plant.

    Wow! UK, France, USA, my tomatoes have gone global! Blue Onion, I think I might give that a go. Being new to all this I have to accept this is a constant learning process and not expect 100% success straight away.

    Is that one closest to the door? perhaps in a draft? It really does look like a physical issue and windburn or just plain drying out can cause that look.

    Scandi - one of them (I've got three Sweet Millions,  three Rosellas and three Gardeners Delight) was closest to the door but the other two were away from the door. My greenhouse is very small and because of the hot weather the door has been open a lot. I am thinking that it could be due to drying out because I was so conscious of avoiding overwatering that I may have gone too far the other way.

    @zakthecat - I grew Sweet Millions for the first time last year, and wasn't overly impressed. I grew Sungold as well for the first time, and they're great.
    Sowed both again this year, and the SMs were terrible to germinate again. Only one out of the three or four appeared. I won't be bothering with them again. Never had a problem with getting any toms to do well.
    Mine are grown undercover, and they were fine once they got going, but I'm not convinced about SM at all. Perhaps it's that simple  :)

    Thanks Fairygirl - maybe it is just the variety. As I said, the Rosellas and the Gardeners Delight seem to be doing okay. Something to bear in mind for next year.

    That's been my experience of them, but it may just have been a poor batch of seed or something. Difficult to say.
    I have no problem germinating toms usually, and the Sungolds were fine, and treated to the same regime. One of those things perhaps  :)
