It is pretty difficult to get potassium into a form that wouldn't
be usable by plants, so I doubt that you have a problem there. The anion
is probably some poorly characterised organic material, which is unlikely
to cause a problem in the sort of quantity you have, but that brings me
to the main problem - this will be a very expensive way of adding potassium.
I got my last lot of potassium sulphate from B&B Hydropopnic Gardens, at
375 McArthur Ave., Vanier (Ottawa). (613 744 6786)
The next time you are in town, go and get a few hundred grams, which
will cost all of a couple of bucks. They are pretty disorganised in that
store, so you may have to help the assistant find the stuff!
