You were probably typing this at the same time that Nemo made his last post lol. I'm not expert either, but that does look like the Ruffled variety to me (which I honestly never saw before) so it likely isn't a calcium deficiency as I originally thought. Now that I know that's the normal look, I kind of like it and may need to keep an eye out for one

Huh... yah, sometimes a post sits on my computer for a while while I do other work related stuff.

Thanks, DJM. And Byron - going by memory (eh, I just checked it), 60 drops = 1 teaspoon.

I have a link to a description of different deficiencies:

Aquarium Plants | My views, Steve Hampton, on how to succeed with aquarium plants

I concur about the ruffled sword, and going by the link above I think we ought to consider calcium. I have MTS and Pond snails - who knows how many.

Here's a spot on the Sword:

Thanks you guys!

Steven

60 drops sounds like too many for a teaspoon... don't go by memory.

I can't really tell well due to lighting, but is the trouble only on the one leaf? If so, it's not likely a deficiency.

What is the issue with MTS? I hear they aren't good for plants but I never see them off of the sand... if I ever see them.

Jeff.

I tend not to agree on the species. I have both E. major and Echinodorus osiris, and I believe the plant in the photos in this thread is the latter. It is also in our profile. Having said that, different tanks can cause many of the species in this genus to grow differently. But the very vertical growth of E. major and the usually distinctive spread out growth of E. osiris leads me to think your plant is the latter. It might take DNA analysis to confirm though.

But this does remind me of something. My E. major in the 115g did begin to fail just as your photo described, and I have moved it into the 20g plant tank as i thought light might be a factor. I acquired 2 of these plants, and a couple years ago one even flowered which is extremely rare when grown submersed, according to Rataj. I have 2 or 3 adventitious plants from that parent now in my 70g and they are growing fine but remaining (after 2 years) very short (5 inches max compared to the parent that grew well over 15 inches) but still vertical.

I agree 60 drops per teaspoon seems off. But 10 drops weekly may be sufficient, I just wanted to put it in perspective as I dose by teaspoon and my 10g gets about 1/2 teaspoon weekly, divided into two doses.

MLS are fine with plants; they will eat dying leaves, but I have hundreds and hundreds of them and have never seen healthy leaves being eaten. They do eat algae off the leaves.

Maybe that's where everyone gets the bad rep for these from, snail on leaf, leaf dying, snail eating. Easy to think the snail might be the culprit I suppose.

I started with 10... not sure how fast they reproduce. I expect to go snail watching after hours sometime out of curiosity.

I think the MTS are good, especially (I heard) because of oxygenating the substrate. I just thought that they might be using up Calcium building their shells - probably not.

They reproduce autonomously, and it is dependent on the availability of their underground food. I have seen a lot lately, and I wonder if they have exhausted their food supply.

I think the problem with the Sword is system-wide, not just one leaf. I think that's why it is drooping. The new leaves are light, light green, which may or may not be normal. But the thing I think is definitely abnormal is the ends of leaves dying and becoming a transparent tan, which progresses in some cases to the stem.

I have a Wikipoedia link on Calcium deficiency, mostly from the terrestrial venue.Calcium deficiency (plant disorder) - Wikipedia, the free encyclopedia

My Ruffled Sword's new leaves are coming up whitish but turn green. I think the healthy new leaves are the ones with red margins.

I might try increasing the the Flourish Comprehensive some, even though the plants seem to be struggling. Maybe they're just not getting enough Comp. I'm starting my new bottle of Comp, 125l I think.

Any thoughts, even suggestions and alterrnative ideas?

Thanks.

New leaves on Echinodorus (as indeed with most plants) are always lighter and they darken as they develop. I have noticed that when I was dosing only once per week, new leaves were much lighter, I guess I would say close to whitish, than when I dose twice a week. So obviously the plants need more of something, whatever nutrient it may be.

I am going to try the additional micro nutrients (Flourish Trace) one of these days to see if that is better than just more Flourish Comp.
