Your Planted 55G
You can have a nicely planted tank with the setup you have, you just need to get the right plants. Your lighting is fine, just subdued or low. If you want to keep your current lighting, then get some plants that prefer low light. Attached is a pic of a 45G with no more lighting than you have. This tank is even taller. I use a couple of 6500K, 32 watt, florescent bulbs.
The ground plants are Anubias and Java fern. The stems are floated close to the light and I have Anacharis (Waterweed) and Pennywort.
Vals need stronger light and some varieties don't tolerate the Seachem liquids very well. There's a form of carbon in the product that's not good for some Vals. If you want to dose liquids, API, Tetra, Earth Juice and Nutrafin are good. I rotate the ferts every few days to give my plants a variety.
Large, weekly water changes provide healthy levels of nitrates, phosphates and sulfates too.
Just a couple of thoughts.
"Fear not my child, just change the tank water."
