JBL Ferropol 24
You might be suffering from magnesium deficiency if you are only adding Mg via the traces mix and have very hard (calcium rich) water. Some of the American EI recipes don't add Mg because of <"differences in geology"> between the USA/UK.
- 1/4 Teaspoon of Seachem Equilibrium (for traces and Calcium + Magnesium). (1.42 ppm Ca, 0.42 ppm Mg, 3.43 ppm K and 0.02 ppm Fe)
- 1/8 Teaspoon of KNO3 (Potassium Nitrate) (5.27 ppm NO3 and 3.32 ppm K)
- 1/32 Teaspoon of KH2PO4 (Potassium Mono Phosphate) (1.61 ppm PO4 and 0.66 ppm K)
