You'd be able to tell, this is a tomatoe with Mosiac

:shock:

Would you be able to see this while the tomato is still green?
If you say yes- then perhaps I havent got mosaic?

I have no idea, as soon as I see something that isnt green, I whip it off ASAP. I can't say.

Pictures make a difference, no leaf mould of course. But pretty much look a text book picture magnesium deficiency to me, you said the treatment did not help at all, try not to over feed and over water at the same time , this can increase symptoms. ( By the way it does not affect fruiting, so treatment is cosmetic.)

TMV does need no insect vector and is widespread, symptoms will vary with variety and strain and severity, but one thing is for sure, most else would have it in your gh by now too, if your tomatoes had it.

So cheer up!
