Whats wrong with plant

My lights came on today and like always I go and check on my tank. I noticed the middle of the leaf on my red rubin sword is starting to deteriorate. Is this lack of nutrients or something. I have to seacham root tabs, one on both sides, about an inch or two from the main base. I dose flourish comp twice a week, the second time is about 3/4 dose. The plant is not new, I've had it in my tank now for a couple months.

Is it just a couple leaves or is it all of them?

Mostly just the inside leaves are like this, but some of the outside leaves are loosing the outside of the leaf. I'm been looking up some and I think it might be a co2 deficiency. I've had the lights on for 8 and half hours a day, which I didn't think was to much. I just lowered it down to just 8 hours now.

I would be less likely to think CO2, and more likely to think an excess of something else in the nutrients. I've never seen what is shown in the photo, is it really a whitish film like that in real life?

There are a lot of nutrients entering this tank. Is there a reason you are dosing Flourish Comp twice weekly? And two Flourish tabs next to a plant is a lot; I've only ever used one about 2 inches from the crown of large swords, replaced every 2 months or so.

The light is not likely an issue, if the plants have been fine for a few months, unless the light was recently changed. This is occurring on new growth (the centre leaves), rather than old.

First this sword has never really grown, just maintained this past couple months.

It's not really a white film, it's like the leaf is disappearing from the inside out. Some of the outside leaves are doing this but on the outside of the leaf and not the inside. So the inside leaves are deteriorating from the inside out and the outside laves are deteriorating from the outside in.

The reason I have two tabs is because the row of grasses behind the sword. I put one on each side so the grasses could get some use out of it too. I dose comp twice a week because I thought I was supposed to with having the two t8 lights. I'll just drop that to once a week then.

Might be potassium deficiency if the leaf tissue is missing. Any other plant issues in this tank?

I consulted my Kasselmann and she writes that this particular cultivar is easy to grow in almost any water, and unwashed sand and medium light intenssity is best for optimum growth. Other sources say a nutritious substrate. So here again we have varying opinions.

Nope everything else in the tank is doing good. The water sprite is doing the best out of everything. But ya, this is the only plant with any problems. The substrate is is washed playsand. The quikrete playsand you recommended.

Lights are two 24" T8, one 6500K and one 5000K over a standard 29 gallon tank.

That should be fine. Light is in the high end of moderate (I only have one tube on my 29g), sand is fine. Not sure what else to suggest. Messing with something just for this plant when everything else is fine can work against you. I don't have great luck with these non-green swords, but in my case I think it is the light.

Sort of funny, my tank seems to be polar opposite of yours. My Red Rubin is doing great but my Water Sprite looks a little rough. I am not too familiar with Water Sprite really so, maybe it is supposed to look like that. I seem to get some brownish growth on it which I nip off but if I took it all, it would really be scraggly. I also dose with Flourish comprehensive 2 times a week but that is more because I change water every 4-5 days so... I don't want it to be without the fertilizer. I have root tabs in the Eco-complete substrate as well. Out of curiosity, what substrate do you have?

I guess if it were me, and it were only affecting a few leaves, I would cut them off and go from there. Like Byron said, It might be too much of something. Maybe try dosing only once a week and see how that works for awhile. I think with plants it is really a practice makes perfect as we all have different water and even at home with more then one tank, each tank is different. One of my tanks I can grow Hygrophilia like it is nobody's business and in the other, it withered and died.

Edit: I see you have sand, we were posting at the same time, I think.

On the water sprite, I'm not sure how it is supposed to be doing. But after having it in my tank for only a couple weeks, it has 6 inch nice furry roots coming down all over. The plant itself isn't quite as green as when I got it, but even the green part seems to be growing fine.

For the red rubin, I think I might just give up on it. I went and talked to they guy that runs the lps here. I'm going to just have him order some other different kinds of swords. No more red i guess, just have to stick with different colors of green now. Anyone have any recommendations for non green plants that do well with moderate light? I was thinking maybe some stem plants just spuratically (sorry can't spell) placed just to add some color to the tank.
