Is there a difference between normal Epsom salts and Horticultural Epsom salts ?

I don't think there is any difference other than one is approved for human consumption whereas the horticultural grade is not.
If all you want is a bit for your tomatoes, then 300g is about £2.50 from your local pharmacy. It should last all season. Pharmaceutical grade is ok for plants (even if its out of date)
