I recently bought some of Valrays Fertilizer on trademe, and now realize that there is a lack of nitrates, I assume this is due to the supplier thinking that there will be fish producing ammonia, nitrites, nitrates ect.
This solutions contains
2% Magnesium Sulfate (MgSO4)
8% Potassium Sulfate (K2SO4)
3% Potassium Nitrate (KNO3)
4% Trace Elements
83% Water
So N:P:K in these ratios 3:0:19? Or am I working these ratios wrong? I beleive the common ratio is 4:1:4.
So do I need to add nitrates? And if I do, where can I source nitrates?
Thanks
