Fingers crossed fo you Tim that it is nothing nasty. Envious of the ripe toms in pic, I devoured my one only ripe one yesterday while checking plants.

Tomato leaf Mould i would say, it affects the lower leaves first with the upper leaves having some yellowish patches.
Remove the lower leaves and create more ventilation leave the greenhouse door open at night.
There is a spray for it but cant remember the name.

Hope this is your problem Tim and not the dreaded whatinfact.

Anything but that!

The leaves are purply black.

Magnesium deficiency? most likely to occur in tomatoes grown on sandy or acid soils, or where high-potassium feeds have been over-applied.

Just discussion, Fork.

Interesting thought but, whereas I normally use a 2-1-4 fertiliser, with good results, I'm being lazy this year using Maxicrop at roughly 5-5-7.

Don't suppose we'll ever know?

PS Just seen yours, Davy. Positively no mould spores on either side. And they are about the only leaves that do not have yellowing! So funny that only 2 of 12 varieties have it.
