Ok I will try bothJust add what it says in the EI article because there is some K in both Pot Nitrate and Pot Phosphate which you are already adding.
The stuff from the plant shop should be as pure as the stuff from aquatics shops. The difference will be that the plant shop will sell it in granular form so you will have to crush it up with a spoon in a bowl or pommel and granite it etc.
You say using EI traces. What trace are you using?
Your defficiency suddenly sounds from your description like it may be magnesium!!! Try dosing epsom salts at an equal measure to the pot sulphate.

I buy epsom salts at a pharmacy?
