Magnesium deficient tomatoes

[mpdjulie]

Yesterday I checked my greenhouse tomatoes and the leaves are showing signs of magnesium deficiency.  I have some magnesium sulphate in the lottie shop, is that the correct thing to use?  Also what ratio to water should I use as the bag of it doesn't bear that information?  How do I administer it to the plants?
Thanks
Julie

Epsom salts is used at 1 tablespoon to a gallon or one tablespoon to every foot of plant

How do I apply it to the plants - water it in the pot or spray it on the leaves?

you can do either but i would apply it as normal watering  once a week

I've just been sprinkling a large pinch onto the compost of each plant and watering in, seems to work.
