Holes? Torn Leaves? Help!

[nikkifro8994]

Hello. I have 1 panted tank for my betta fish. It's a 5 gallon tank with 1 amazon sword, 2 gold ribbons?, 1 small Anubis, and 1 small moss ball. It's not by the window so I have to use artificial light. I have a blue bulb in the hood. All of the plants look fine except for my amazon sword. It has holes in 1 leaf and 1 leaf is torn off at the top. I use API Leaf Zone as fertilizer. What happened to my sword? Also, what type of light bulb should I have?
Thanks!
Nikki
