Tomato leaf query

Hello,

I've recently started growing tomatoes for the second year, after picking up gardening during lockdown and seriously getting the bug for it!

I've got some (many) tomato plants underway but a few have been getting a similar issue with their leaves. It seems to be older leaves on them but I'm just after some advice on if it's anything to be concerned about.


I hope the picture attaches, but they're basically getting some small yellow spots which progress into more of the leaf being yellow ish with green veins still. I read this could be magnesium deficiency, so I attempted over a few weeks to add epsom salts in to one plant but it hasn't made much difference. This is happening to a few different varieties, and seems to be the greenhouse grown ones more than indoor ones.

Any ideas? Is it anything that needs to be worried about or correcting?

Thanks for any advice!

    It's quite common for older leaves to die back, but it's difficult to tell just from those photos as we're not seeing the whole plant and how it's being grown.
    It can sometimes be water getting on the leaves, and creating a bit of damage if the foliage is against glass on a sunny day, but if the plant is otherwise healthy, it won't be a problem. On a larger plant it's perfectly normal for older leaves to die off as the plant matures.

    If they've been potted on appropriately, they shouldn't be short of nutrients unless there's something very wrong with the compost. 
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...

    Potted on fairly regular :) I'll take another few pics tomorrow! None of the damaged ones have been against the glass. Could be water on the leaves though, been a few humid days in there in that summer we had in April ha ha. There's one plant that's suffered particularly with it but could just be luck of the draw I guess!?
