Scary - wonder how we ever manage to get a crop at all with so many nasties out to get us.  Thanks for the link - It will be useful.

A good start, but where do all mine fit in??

Yes, a good place to begin... the trouble is, that it's so hard to identify what's really behind a problem. My plant illnesses very rarely fit the pictures, they must use a different guide!

Say you have the purple leaves that many of us have had this year. The general consensus is is that the weather has prevented the plant from functioning properly. I think that this has resulted in plants being less efficient at taking up a trace element.

So, this would show up as a deficiency on a guide but it was the weather really...

You can't really see how serious this is.

TIM, I have to say i am stumped, all the signs say Tomato Leaf Mold and Magnesium Deficiency but you would no that.
So i can only think of two things that may cause this problem one which we discussed, using last years Grow Bags and a possible deficiency of minerals in them.
The only other is your water source. I keep looking at the pictures and wondering about the salt content  either in your water or in the grow bag being to much for the plant. Does that make sense.

As Davyw1 said, I don't think that your compost is holding onto the nutrients well enough and they're all getting washed through. I'd re-pot, but as an alternative you could use a manure liquid feed to reintroduce some of those lost humus molecules.
