Foliage not doing so well...

[Grits]

I have an Amazon Sword and a Hygrophila They both looked pretty good for a while. They all have really good root systems still. But the foliage is going down hill.

The Amazon Sword leaves are getting holes in them, you can see through them, and the tips of the leaves are turning yellow.

The Hygrophilia is getting new growth at the top but the lower leaves are turning black around the edges and kind of curling up.

Thanks in advance!

Thank you!

It's a 75 gallon tank. I have 1 40 watt Power-Glo 18,000K light.

No CO2.

I haven't added any fertilizer yet. I don't know the first thing about that and I don't want to hurt the fish. I have:

1 Red Tail Shark
1 Rainbow Shark
2 Clown Loaches
3 Spotted Corydoras
1 Zebra Bottia
2 Golden Rams
2 Black Iridescent Swordtails
2 common plecs

You don't have enough light for your plants. Your aquarium is in the Very Low Light category and there only a handful of plants that will have a chance of surviving unless you upgrade your lighting.

I'd recommend sticking to Anubias, Java Ferns, and Java Moss under your current aquarium conditions.
