I set up my fish tank and i realised that the plants are turning bit yellow they look burnt. I went to go and look at the light and its 11 watt. I have no fish at the moment but I am planning to get Siamese fighting fish.

I think the general is 2 watts per gallon. If it is an incandescent (which most tanks come stock with unless otherwise specified) it is not providing any usable light for your plants.

On a side note, you are just getting ONE Siamese fighting fish, correct?

what kind of tank/hood light are you using?what kind of bulb is it?incandescent,flourescent?how long are the lights on everyday? how long has the tank been set up? what kind of substrate and plants?any fertilizers being used?what are your water parameter readings? i know it seems like a lot of questions.the more info we have will better help us understand what is going on in your tank.

The light is fluorescent, I started the tank week ago, I have the light on for 10 - 12 hours day. I haven't used any fertiliser for the plants, i forgot what the plants are called but here picture of my tanks (btw its no longer cloudy anymore)

cut back to 8 hrs. they are probably adjusting to your tank. the plant on the left looks like bolbitis. does it have a horizontal stem that the leaves come out of?the one on the left looks like a sword plant that has been grown emersed.it may lose most of its leaves. if they look like they are dying,snip them off with a scissor.this way the plant will put its energy into forming new leaves instead of spending its energy trying to keep dying leaves alive.the other plant will do better if removed from the pot.if it is bolbitis it will need to be attached to some hardscape.

the hygro was kinda hard to tell from the photos. from the photos the leaves look kinda heart shaped.thats why i thought it was bolbitis.hygro has spear shaped leaves.the veining looks right for hygro though.hygro is an indicator plant.it is often the first to show defiviencies,especially potassium.this will show up as pinholes.were you able to look at the bulb and find a kelvin rating?you want one with a rating between 5000-8000k with 6500k being the ideal.
