OK Gareth, I'm confused. You ordered phosphate salt, which is a critical requirement and the vendor sends you sulfate salt, of which you need very little...and you continue to use the sulfate in lieu of getting the order corrected to phosphate? There is no way on Gods green earth that K2SO4 can make up for a PO4 shortage. It's not even remotely possible. Furthermore, since you are already dosing KNO3 you have all the K you'll ever need. In this context the K2SO4 is completely useless. Am I missing something?Garuf said:I really don't know, the flow has always seemed low but every variation of theme to improve it does nothing.
I'm dosing MGSO4, KNO3 and KSO4
My recipe is
1teaspoon of KSO4* (this is what AE sent me when I ordered KH2PO4)
2 1/2 teaspoons of KNO3
6 teaspoons of MGSO4
All teaspoons are heaped and well on the generous side. I then add this to water and dose accordingly every other day.
