Just thought I'd bump this since I didn't get much of a response.
My plants have seemingly good color, but the leaves are "crinkly" and the stems appear weak and thin. Almost every plant I've added was stout and had good form, initially, but with the new growth in my tank it's just not quite as nice looking. There is a lot of new growth, though. My pigmy chain sword is, of course, taking over the tank--but it's not quite as frail looking, for some reason, as ,for instance, my microsword, anacharis and tropic sunset. I also have dwarfhair grass in the tank but it looks okay, despite a lack of new growth in the brightest section of the tank.
I have a 2.5 gallon with a 9w 6700k corelife CF bulb and a 1.5" substrate, laterite at the bottom, TMS above it and some plain washed gravel at the very top. I really didn't know much about substrates at the time, so this was my attempt to keep the laterite from fogging up the water too much and the plain gravel is used to help anchor plants. I give the tank a small dose of straight flourish every few days and I depend on food for nitrates and phosphates.
