Corals brown and not growing much

[Armon_p]

Hello
I have many sps corals like montipora and acropora, they are brown.
I bought them with color but they lost most of it and turn brown and they don't grow much after months.
I run kessil 350w full intensity and have perfect water parameters.

Please help
