For the record, when I have used potassium gluconate, I think
its been to increase potassium by 5mg/L or so. I have not had a
white residue or other problems.
I think I agree that for larger doses you don't want potassium
gluconate. It's just not cost effective. But the value in the product is
its convenience. If you have a suspected potassium deficiency, this
is a good way to find out. Having established that, you can continue
its use or find K2SO4.
I have read the label on my potassium gluconate and am not overly
worried about the gluconate. ( its used too much already in the
aquarium industry ) But not knowing a whole lot about "binders"
used in vitamins and minerals, I think from now on I'll forgo the
convenience of it and dose with K2SO4. I have mine from Homegrown
Hydroponics ( 416) 242-GROW. 500g was quite cheap.
