I've been lurking for quite a while, and this is my first post as I am in need of some expert assistance.
I've had my 150 gallon tank running for 8 months now, in the beginning my plants were growing fine and then Nov-Dec my plants started deteriorating and now I'm left with pretty much just stalks, and I've lost a few plants lately.
I have had no issues with the fish in the tank, just the plants. In fact all of my fish are exhibiting mating/spawning behaviours, which I took to be a good sign.
In the past three weeks I've changed my bulbs, added root fertilizer tabs, and started a weekly dosing regime of 2 tsp Florish Excel, 1 tsp of KN03, and 1/4 tsp of KH2P04.
So far things aren't getting better.
My goal is to have a nice thinkly planted tank with lots of community colourful fish, looking to get lots of vals and other long grass type plants - but they don't last they just disintigrate (sp?).
I'm also trying to avoid going with a pressurized co2 system.
So what am I doing wrong? What should I be doing? Any assistance is greatly appreciated! Any suggested readings?

Test results from last night before a water change 0 ammonia, 0 nitrite, 5 nitrate. I haven't checked pH for a while, but if memory serves it was 7.2 or 7.4. I have not check for water hardness.
I have been doing bi-weekly 50% water changes, and am now starting (2nd week) of doing weekly 20-25% water changes; although last night's change was 50%.
Fertilizers - into 2nd week. Weekly add 2 tsp Florish Excel, 1 tsp of KN03, and 1/4 tsp of KH2P04.
