Hi, i have a couple of aquarium onion plants in my tank. I've noticed that one of the leaves is turning brown from the top of the leaf down. It's grown to about half an inch of brown over the past few days. This is a relatively new tank and was just cycled about a week ago. I tested the Nitrates today and it came out at between 5-10ppm.
I dose Excel carbon every couple of days and i've been giving liquid ferts twice a week. Do i need to up the ferts until the Nitrates hit 20ppm? I understand that's the ideal.
Light levels are at 1.5w per gal and i leave them on for about 8-9 hours a day. The Java ferns and Anubias in the tank seem to be doing okay, although i noticed a couple of the java fern leaves turning a darker green. Again, is this a sign of needing more ferts?
Thanks!
