How long do you have your lights on each day?

Recommend 8 hours approx.

You havnt buried the rhyzome on the plant have you?

[jerome]

8h per day.
nope, there is new leaves growing out but the old one will turn brown.

probably just adjusting from emerse to submerse. Note that most of the plant sell in LFS is grown emerse.

I second what Shadow said, certainly the logical reason. Just have patience, if in a month or two it is still showing no signs of prolonged healthy growth then check back.

If its adapting new submersed leaves will grow, and the older emersed leaves will die off. So no worries
