Doing EI per week
I am doing next week an EI procedure to my planted tank. My question is can i only dose once per week?
Meaning, i dose 20ppm of N, 30ppm K and 3ppm of PO4. I dose Fe on the next day since i know dosing Fe and PO4 at the same time will precipitate Fe (though, i do not know if this true).
I am always not at home on weekdays and will be only available on weekends that i why I want to know if this will works?
