Brown Spots

[Rocknrobyn]

What is going on with my plants. They are all turning brown. I just changed my light to a better light with the right wattage and I have 4 platys loaches tetra and a cory in a 21 gallons tank... I posted sum pictures..

At first glance I'd say that the better light has increased the plant's metabolism and thus it's need for CO2 and/or nutrients. But we'd need more info for a proper idea.

Tank size
What type of light? (t8, t5, metal halide?). And how many watts?
I'm guessing you dont supply the plants with any CO2 or nutrients?
Filter flow rate (litres per hour or gallons per hour)?
What is your maitenance regime?

I do put flourish tabs in the tank and my tank size is 21 gallons and I don't know how to tell what my filter flow rate. (Im a newbie)
My lighting is a t5 and I have 28 watts going. I just bought this about 2 weeks ago...
