Hello Blu...
Trying to maintain a specific water chemistry takes work and isn't necessary to have a healthy, well planted tank. You just need to have a steady water chemistry. Keep hardy, easy to care for aquatic plants like Anubias, Java fern, Banana plants, Swords and Onion plants. These will easily tolerate more acidic water.
To maintain a steady water chemistry, avoid putting chemicals and such in the tank water and just use a standard treatment to remove the chlorine and chloramines. Change most of the water every few days to maintain good levels of the trace minerals the plants use and you'll have a nicely planted tank.
Keep tank keeping simpler and you'll be more successful.
