Well… then I just must be doing it wrong. I’m doing A and Epson salt together. Then after those two dissolve together, then adding Part B
Bought mine in ebay… people buy large quantities and then repacked in reasonable quantities for growers like me
Is Part A: 15-12-26 and Part B 15-0-0?
Part A, let it dissolve thoroughly, Epsom then Part B.
I got 2.2 lb bags direct from them.
