What is wrong with my old leaves?
This is happening to the old leaves on mostly my Anubias Nana and my Dwarf Sag. I dose with my goodies mixed up from Greg Watson per the Sears Conlin formula. My nitrate is always 5-10 and phosphate is usually .5. I dose ~5ml or so every few days and change 50% of the water every other week.
Here is a pic of the old Nana leaves, the newer leaves look ok, you can also see some of my dwarf sag in the pic.
Here is my whole patch of Anubias Nana and some of my dwarf sag.
Thanks for any help!
