I dose excel daily. I am using EI low light dosing as per online calculator. But as someone stated anubia leaf yellowing seems to indicate N deficiency so I'm confused. I do have relatively fast growing stems ie water sprite, pennywort and even my cabomba seem to put on noticeable growth daily. My N levels are 5 ppm and P levels are 0.25ppm which suggests I need more fert even without CO2
I should clarify, the fert schedule I mentioned earlier is actually less than recommended by low light EI and I have actually just increased fert dosing this week. So far no explosion of algae but somehow does not feel like low tech anymore lol.
