Ludwigia Repens Rubin

[Unexpected]

Is there a specific cause for the curling in these leaves?

GH 5.2 (24ppm Ca, 8ppm Mg)
28ppm NO3
8ppm PO4
31ppm K

Burr's Micro mix .45Fe as proxy.

Pool Filter Sand substrate.

Thanks for any insight.

Rubin leaves arent gonna be completely flat but those are a little unhappy right now. Are they newly acquired? If they're tops you replanted try going with longer ones next time. Its a tough easy plant and grows fine in sand. Will probably grow out of it

Glandulosa (in back) has flat leaves

They are new plants and I believe they were emersed prior to going into my tank. I just topped and replanted them last Tuesday.
