sword problem

[AngelWings]

Hi all!
I purchased a beautiful new Amazon swords a couple weeks ago and it arrived full and gorgeous. About 20 inches tall, maybe more. After a couple weeks I've noticed that the leaves are doing this. I'm assuming it's a nutrient deficiency, but does anyone know what it needs?

If course, now the picture won't post. I'll keep trying.

Do you have root tabs under them? They are heavy root feeders. What's your lighting like? Also of note ,expect to lose some of your sword leaves as this is normal, as long as its showing healthy new growth it will be fine.

I do have root tabs under them, regular root tabs, iron, and potassium. The lighting is 10k metal halide.
I'm worried that many of the leaves seem to be doing this at the same time.

It may be adapting to your tank. Are there any new leaves growing?
