Planted out my tomatoes last week and already they are showing yellowing on the older leaves.  I remember from last year that Epsom Salts did the trick on this but can't remember what dilution to use.  I bought the pack in the Chemist and not in the Garden Centre so there are no instructions for feeding tomato plants on the container

I just sprinkle a spoonful of Epsom salts on the compost and water in.
Never killed a plant so far !

I added a tablespoon to a large can of water, raspberries got some last week. They ain't dead yet.

Thanks folks, we have no water at the plot at the moment (council doing some Road works burst the mains).  As soon as it is back I will give them a good dose of Epsom Salt and see how I get on.
