I'm a little curious about using Botanicare Sweet. I'm all for carbs, but why is there epsom salt in the formula, and can it build-up to toxic levels? Is it simply a ph adjuster? Are there epsom salts in all of the carbo loads?

Using Fox Farms, I'm aware of the problems that salt build-up presents. I flush often enough for me not to worry, (monthly) but what about others out there...should they be concerned?

How about the interaction between Sweet and molasses? Does one synergetically improve or (on the other extreme) make toxic, the other?

Also...any clues why it's listed as epsom salt, and not magnesium sulphate? I have always thought that the epsom salts were for household use, and that magnesium sulphate was 'different' and intended for agriculture. Evidentally not, huh?
