Plants Are Looking Abit Brown N Dead?

[Buddy33]

hey guys i just have a problem, pretty much all my plants are turning brown n dying? just would like to know if there is any thing i can do to liven them up?
i have a grow lite thats on 4 12hours a day and put some tablet fertolizer in about a month ago but still brown??

brown usually indicates a lack of iron or nutrients in the water... I suggest getting a liquid fertiliser as a quick fix, however, you may want to look into getting a specific substrate that provides a large amount of nutrients directly into the root system

a specific substrate - whats that

 

[Carter]

Red Sea Flora+

cut your lighting to 8hrs a day, it will stop the plants needing more nutrients.
I would avoid the red sea florabase as it can tun to sludge after a while. Getting a nutrient rich substrate will help however if you do not want to change then i would buy a decent fertiliser such as seachem flourish or tropica plant nutrition+
What plants are dying?
What size tank?
what lighting do you have? Diameter and wattage.

thanks

really? hmmm... i may want to investigate into the red sea substrate...

thanks aaron

ok, well i have some Ambulia, Magenta, and another type but dont no its name,
my tank size is 150L 3ft
i have a 36" long 30W power-glo

not sure what magenta is? Can you find a picture? And also a picture of the unknown plant.
It may be non-aquatic hence why it is browning.
