Amazon Sword nutrient deficient?

[svachon9]

Ok so is this a nutrient deficiency?  It's a Am Sword and I have given it a lot of root tabs.  I am a bit light on Easy Green though.

Light has been only 7 hr but I've bumped it up to 8 hrs with 60% intensity. It's a Coop light which is quite powerful with the amount of lumens.

 

 

Also 90 gallon tank.  Low tech- no CO2.

How long have you had the sword? Those look like the round emersed leaves. If it is a new plant it's nothing to worry about. Just the plant losing its old leaves to grow its water leaves.

3 months and it was growing new leaves.

I was going to say the same thing that they looked like emersed leaves. If they were outer leaves, it is possible that they still are.

Did all of the new leaves turn yellow and melt too? Do you have a picture of the full plant?

id not worry about the old leaves. keep an eye on the condition of the new leaves. sometimes it takes many months for the emersed grown leaves to die off.
