Amazon Sword leaves turning brown.
 
Every couple of weeks or so I have a few leaves on my Amazon Swords that turn yellow and then brown. Of course I trim these off but I was just wondering why this is happening? I always get new growth but I really want these plants to fill out. I put one root tab in between both plants a few weeks ago. Should I add another? Any help is appreciated.

What's your GH?? Also do you add any liquid fertilizers??

Post a pic, mine are doing that too but the leaves were brown spotted from the store. I figure as long as the new leaves coming up are at least as numerous as the trimmings, they are fine... I'm getting ahead with more growth than trimming right now but I think that they were languishing at the store for a while before my wife rescued them.

That rapid a die-off of older leaves is not normal, so something is wrong. In addition to the data Boredom mentioned, what is the light (be specific)?

I'll have to get the GH tomorrow. I use Seachem Flourish Comprehensive liquid fertilizer and Seachem root tabs in between the two Swords. As for light its a Aqueon NO T5 with one 6500k Daylight and one 6700k colormax.

To put the light in perspective, what size tank (length and volume), what length are the two tubes, and what is the daily duration? Flourish once or twice weekly? This plus the GH should help us.

The tank is a normal 4ft 75g, tubes are 4ft on for 11hrs a day and dose every Monday and Thursday.

GH is between 0 and 30 and KH is 40 using API test strips.

If thats ppm then you DGH is less then 2. That's pretty soft water in fact a little too soft for plant. Plants usually do best with a hardness of no less then 5-6. Anything less than that then the water lacks minerals for the plants. This is some other problem and I will let Byron (or anyone else) weight in on this as I have water around 5-7 in my tanks and never had to raise the hardness. Also your lights (tubes and length) seem fine too me but I wonder if having them on for 11 hours is some other problem as well. Do you have other plants in this tank? If so are they showing problems?

I knew I had very soft water but that is the only plant not doing well. I have a bunch of different species in all my tanks. My moneywort tiger lotus and anachris grow like weeds. I don't know if its normal for these plants or not.
