Sword ID and What's Wrong with It


[Pic below]

I think this is a Ruffled Sword (Echinodorus major) It's in a 10g tank. I also think there is a nutrient deficiency. Another plant has pinholes, but not this one that I can tell. Maybe it's all right and I can just add some potassiium for the other plant.

I put in a new Root Tab under the Sword last week, and there has been a new leaf every couple of days. Changed lighting from 2x 10w CFL to 1x 13w last week. A lot of plants haven't been growing, although some are. Please notice the dead translucent area on the end of the Sword's leaf on the right.

Please let me know what your thoughts are.

Thanks.

You can pinch off that dying leaf when it gets a little worse. While some of it is still green, it's still producing energy for the plant.

I've got an amazon sword right now that's doing the same thing on one leaf. I'll have to prune it soon.

Some plants take a while to adjust to new ferts or lighting conditions. You may see little or no growth for several days when that happens.

I don't see anything wrong with the sword in question here, if theres pinholes that could be caused by a lack of potassium i believe.

If its newly planted no prob at all. Some plants have slight bruises during shipping, melt leaves while they are still adjusting and develops those translucent areas due to stress. Swords are very easy plants and establishes itself very fast.

No, unfortunately, I've had it for at least five or six months, but maybe it will settle down after a bit. I'll dose the tank with a little Potassium for the other plant and they will also get used to the new lighting. I would really hate to lose this one though.

I'm using FlourishTabs. They have soluble potash (K2O) 0.16%, Phosphorous (P2O5) 0.17%, Nitrogen 0.28% and trace minerals.

I also use Flourish Comprehensive (micros?) that also has Potassium - I can buy a pound of it for $3.00 at Greenleaf Aquarium. I wonder if in addition to KNO3 I should get a pound of Phosphorous too? Shipping is probably the same if I'm not mistaken.

Otherwise maybe there isn't anything wrong with the Sword. I've been dosing Flourish Comp. for some time now. Maybe it just wants more, or the lights were too bright - I strongly suspect they were - I had two 10w CFLs and switched to one 13w CFL last week. For the mean time I guess I'll check the nitrates and see where they are and if necessary, I'll go to twice a week.

Anyone have any recommendations on this? Thanks.

It looks pretty good to me. They say swords are heavy root feeders so keep up with the root tabs.

yah, it looks good to me as well
gunna echo everyone else and say keep up the root ferts
My swords take forever to establish, and then they grow so slowly for me.......
But once they get a hold they start doing pretty well for themselves.
