New Pics

So today I found a Red wendtii. I have found this plant once before locally but was pathetic. This one was big enough to split into two plants so I did that. I took some more hopefully better pics today also.

Just did a trimming yesterday as my pennywort and Jungle Vals were over running the top of the tank to the point it was hard to find "open" water to feed the fish. I might have cut too much though

Also any suggestion on what to replace the Jungle Val with? I like the look of it but it gets sooo hugh! Also if you cut the leaves it seems to growing but it also seems to encourage it to send out runners more.

Anyways here are some pics not the best and over look the brown spots on my Sword as I know they are nutrient deficiency spots. I got to get better at dosing fertilizers on a regular bases. So it all comes down to me knowing and still forgetting.

Looking good! My vals are spending out runners.

Thanks Jayy! I don't think so and frankly am mad at myself for letting it get to this point. The pics really don't show what I am talking about except for the one with the shrimp. Most of the leaves on my sword are this way well I wouldn't say most a lot is a better word. My vals are or were getting soo long that they were getting tangled together along with the Pennywort. That was just a mess! Am looking for something that's similar to the Jungle Val as I like the looks of them just not how tall they get.

The brown spots are likely due to an excess of iron. What ferts and how often? And what is your GH?

For an alternative to the Valls, there is Sagitarria subulata that grows tallish and very narrow leaf. There is an Echinodorus that grows much the same, with slightly wider leaves than the Sag, I think it is E. uruguayensis.

Well if it is excess Iron then it must be coming from my soil substrate but heres the deal. I have not and I am ashamed to say but I haven't actually dosed any fertilizer for about 3 weeks now. There are some root tablets there by the Sword. I know there is at least 1 if not 2 near by the sword. This is why I just assumed it was a deficiency not an excess hmmmm .... Maybe to many tablets near by but those are from Flourish so they shouldn't be unbalanced or have more iron then the rest of the nutrients. I also don't dose just iron or haven't added anything like clay for Iron. So not sure there.
My GH is 10 the best I can remember. Also didn't mention the liquid fertilizer is Flourish Comprehensive.

Diagnosing nutrient issues is not easy, as many different deficiencies can have much the same appearance. Deficiencies and excesses can also be caused by some other nutrient being in excess or deficient. Brown blotches can be caused by an accumulation of iron when calcium is deficient, but also it may indicate iron deficiency, and I believe potassium deficiency. Knowing which this may be can sometimes require experimenting unless a deficiency of one of these is a known certainty. In my case when my swords all developed these brown blotches it turned out to be calcium deficiency allowing iron to accumulate.

In your case I would doubt this as the GH is 10 which is fine for calcium and likely magnesium. Potassium may be deficient however, as this would result from the lack of liquid fertilizers which you've mentioned. Plants can only take up potassium as an ion directly from the water, not the substrate. Potassium in the substrate is thought to possibly increase the availability of ammonium to plant roots.

If this is something that was not occurring previously, I would simply get back to dosing Flourish Comp once or twice a week and after a couple weeks observe the plants' reaction. This deficiency is usually on old leaves (outer leaves) first, so if newer leaves (those within the crown) do not show this, problem solved. The existing blotchy leaves will not change, and it is up to you to leave them or cut them off. Some nutrients within the leaves are mobile, meaning the plant can transfer them from old leaves to new growth. If the stem at the crown is brown, the leaf is basically dead and with no connecting veins this can't occur so removal of the leaf is best. But if the stem is still white then the plant is able to move nutrients up and down.

It only takes a couple weeks in my experience for issues to become evidence due to nutrient changes, so there you are.

Byron.

Thats something I wasn't aware of, I assumed (and obviously assumed wrong here.) that with heavy root feeding plants such as Swords and Jungle Vals that root tablets would be fine. Now I generally dose liquid ferts as well and did this week once already. Things here lately have been crazy at my house and I haven't been dosing the fertilizers like I should. I will change that and now that I know liquid fertilizers are a must with any plant I will not be leaving it out anymore. Thanks Byron for the help.

You're welcome. We continue to learn. I've been having potassium issues too, on top of the calcium, so I learn as I go and try to pass on what I learn. I think my disappointment with the enriched substrate is connected to all this; I found it odd that I had to still dose Comp in this tank same as the sand/gravel substrate tanks, and the plants were about the same in all.

So I look at some pics of the Uruguay Sword (E. Uruguayensis). Not sure if that will achieve the same effect as the Vals although it looks like a very nice sword.
