I can't seem to find the answer, I must be looking right past it and can't remember from last time I mixed up a batch of fertilizer. So I was hoping someone could tell me how much of PPMD to mix up into a dry stock for direct dosing into my tanks. What parts of each I need to add of NPK, CSM+B, and roughly, how much iron powder also. I have EPTA iron, 13%. I don't have an iron test kit but my plants start suffering without iron supplement so I need to add some to my dry mix.
Hope my question makes sense and someone can point me towards the "recipe" I need. I promise I'll write it down this time!
