Whats wrong with my plant? (pics)

OK, here's my plan of action - I bought a Phosphate test kit and Flourish root tabs from Big Als, and they should be here soon. A couple of ppl on different forums have recommended that I dose HALF of what the bottle says to dose on the Flourish products, since I only have a moderate light tank (2wpg). I also plan to stop dosing PO4 and NO3 completely because I faith in my pictus and oscar to make enough of it :p and to also stop dosing the Fe almost completely, since the Flourish has some in it already. I planned on:

Flourish = 1/2 cap ful weekly
Flourish Excel = 1/2 cap ful daily
Flourish Iron = 1/2 cap ful monthly
Flourish Nitrogen = as needed
Flourish Phospate = as needed
Flourish Potassium = 1/2 cap ful twice a week


How does this sound to you guys? Do I need to up something or cutback on something? Please critique!
