Vallisneria breaking off and yellowing!
Maybe someone can help me with my Val problem. They keep turning yellow and breaking off and eventually the entire stem dies. At first I thought it was not enough potassium, but I started dosing seachem Postassium and it's still happening. Do I need more nitrogen?
I have no problem growing new plants, but the longer ones continue to die.
I does flourish, iron, and potassium. Stopped excel because I was told it melts vals, but it's still melting without it. No CO2.
