Amazon Sword Mineral Deficiency?

I have an Amazon sword plant that seems to be booming with growth. It is growing a whole new leaf about every 2-3 days.

The plant is looking great but more recently, it looks as though it may have some sort of deficiency in nutrients based on the new growth showing. It seems as though the leaves are still green coming through, but the veins are a light brown color (see photo). Makes me think it may be sulfur or a mineral missing, but wouldn't the two root tabs I have at the base be covering that mineral supplementation? None of my other plants are showing any signs of any deficiency. Maybe it is normal, because as the leaves mature the veins do eventually turn green?




I'm dosing Iron daily, have 2 flourish root tabs at its base, as well as dosing potassium every other day. I'm also running the Fluval minI CO2 kit (which is making a surprising difference for my plants) and dosing flourish excel every other day to supplement the carbon. My nitrates are holding steady at about 5-10ppm. I also have seachem flourite substrate.

Any insight would be appreciated!

Best Regards

 

Do you also dose micronutrients? That's what I'd try, though as the leaves seem to be growing out of it I don't think it's too serious.

 

There are quite a few micronutrients in the flourish comprehensive (once a week) and flourish root tabs I'm using. Should I also be using something like Flourish Trace?

 

I would try it. It could be something really obscure that only affects the young leaves. Can't hurt to try it! Otherwise, I don't know...

 

I read some other article on aquatic plant central where the person took pictures and posed the same question I just did... he was told by multiple people that it was normal for new leaves to come in like that on a healthy plant. I've never had a sword so I wouldn't know any different.

 

That looks fine

 

Sounds good to me! I've only had an Ozelot sword so I've no idea what's "normal" for other varieties

 

some even will show complete red leaves
