Ok, so I have a Java Fern (wendelov?) that's been in my tank for a week now. Lots of the leaves are turning black, and I can't figure out why. It seemed to be doing fine earlier.
Also, all my hairgrass seems to be turning a clear/brown. Its all in my 10g, and the hairgrass has been in there about a month now (but it did just fine the first week and a half! even had new runners!?).
I'm doing weekly water changes, water temp is usually between 78-82*F (for the most part it sticks at 80 and doesn't go higher unless I forget to put the A/C on when I go out), and I dose with API Leafzone once a week when I change the water.
Here's a few pics:
