Plants going brown.

Shekoi

Trying to start up again
in my 40g some of the plants have gone brown, mainly the Cryptocoryne beckettii and the java fern. What could be the problem. The light is on from 7am untill 11pm. i have just moved the tank to my new place, i can't remember if they were brown before.

Can the plants be saved?

see 40g tank link below for equipment and food details.
 
What are the pH and KH of your tank water just before the lights come on?

Do you have recent NO3 measurements? PO4?

Is there ANY algae in your tank? What kind?

What is in this plant grow formula of yours? (nutrients & percentage) What is your fert. regime?
