Default leaves are growing curled

I have several Alternanthera reineckii plants, and one of them has leaves that are growing curled longitudinaly.
Does anyone have any suggestions as to why these leaves are growing like this???

it almost looks as though the leaves aren't opening up all the way. plant is in the same position as other reineckii
3wpg, co2 and your typical fert dose

Maybe you can check on the kinds of nutrients you might lack in your water column - both macro/micronutrients e.g. iron, npk etc. I am not sure of what kinds of nutrient alternaria needs the most, although I have some of them growing in my tanks. However, mine has been growing quite robustly with basic soils, brand-less fertilizer tabs and occasional dosing, around 10 drips of liquid fert every other day.

Maybe you can enlighten us on the types of substrate you are using and the types of fertilizers you dose, it might ease the process of helping you.

It would help if you posted pics, and your tank specs.

What about the other plants? Any problems there?

thank you for the replies...here is more information as requested:

No other plant has the symptom of leaves growing curled, and this is the only symptom of this one plant. It is growing well, and leaves are a rich red to magenta color as they should be.

I use flourish products for dosing and substrate. Excel, flourish, iron, and something called "plant gro NPK" by Nutrafin which doses N, K, and P. Tank has been established for two years, with a substrate suplement added about 8-9 months ago(I cannot recall the brand of suplement though). I really don't test my levels like I should since my plant growth is what I want and I do not have alot of algea growth. I usually dose flourish and flourish iron 1-2 times/week. Excel is daily 10 ml, and NPK dosed every other day.

I use RO water exclusively, w/25% h2o changes roughly every 1-2 weeks.

peat filtration

I personally do not believe this is fert related.

Picture...I turned the lights on for this, so the alternanthera aren't open all the way. You can see the plants on the left side are healthy leaves, and the one behind and in the center has the curled leaves

Let the plant establish a better root system. When I first plant my rotala green, the pants will grow in curled. After trimming it, the plant has enough of a root system to pull the missing nutrients from the gravel and the leaves grow in fine.

Are you reconstituting your RO water? If not that is exactly the problem. RO water will have no GH or KH, and must be reconstituted. Your plants aren't receiving enough magnesium or calcium if you're not based on what you posted you were adding. I used a product called RO Right when I used RO water years ago, and it did the job well. There are other products, but that one had a chart to tell you just how much to add to get the KH & GH where you wanted it.

I am using RO right to condition my RO, I add enough for the discus mix. I believe that is 1/4 tsp/10gal???

Also, the plant with curled leaves has been in the tank for well over a month, and just as long as the other alternanthera. I think its root system is just as good as the other plants.

any other ideas???
