I noticed a couple things that might explain your problem.
#1. Your CO2. By 1.5 bpm, do you mean 1.5 bubbles per MINUTE? If so, that is far too low to add the carbon the plants need under that much light. 1.5 bubbles per second would sound better, but bubble count is purely subjective - a measure for your tank only. This is used once you have objectively measured your CO2 (do a search on here for "drop checker", easy way to accurately gauge your in-tank CO2 ppm.) to keep in a similar range. For example, just running the CO2 line into your aquarium @ 1 bps would give much different results than running it through a diffuser or reactor @ 1 bps.
#2. Nutrients. The presence of algae does not mean that there are adequate nutrients in the tank to grow plants. You will need to add Macro nutrients for the plants to live/grow. Nitrogen/Phosphorous/Potassium, plus trace elements(which you already have, in the form of the Flourish). There are many different fertilizing plans available, depending on how you want your tank to grow. Take a look in the Science of Aquatic Fertilizing section on here for some ideas of what might work for you - look at the PPS-Pro and the EI plans for a general idea. But remember, plants need far more carbon than anything else to grow, so straighten out your co2 first.
#3. Light - Your lights are nice, but they might be too much without the first two elements i mentioned in place. The problem with too much light is you run into problems (algae) very quickly. Maybe try only using 2 of the 4 bulbs until you feel comfortable with everything else. It will still be plenty to grow the plants you have.
#4. very general in nature, spend a couple hours reading up on some of the "how to" threads/articles on here, and don't get too frustrated.
Good luck!
