Help! White tips on new growth on purple cabomba
In the past day or two I’ve begun to see white tips on mostly the new grown on my purple cabomba. There is also a bit on long green hair algae that’s sprouted up in the tank in the past two weeks but not very much (just in case there’s a standard correlation).
Does anyone know what deficiency the white tips usually indicates?
It’s a low tech tank with medium light. I’m fertilizing with NilocG micro and macro with excel.
The my red dwarf lillies are very happy as are S Reppens if that helps at all.
I’ve heard the Cabomba wants a lot of Potassium but from what I’ve read this doesn’t match up low K2O
