the lighting is wide spec flors but i just installed that today. so thats not the prob i;ve been running 24/0 for 5 days now. the plant is 13 days old now. i watered it yester day with 500 ML of water ((about 2 cups)) but it didnt need much i drained 400 mls back out from the tray i had under it.

do you kow whats up with it and if so should i trim off the brown leaves?
