someone help plz brown dots

hi here the pic its not good pic but can some one help plz 2 weeks old very worried about brown dots

cant realy see them on tht pic but anyhow can anyone help

Yeah, it's a bad pic.
Whats ur PH levels?..temp?..what are you feeding it?
Brown spots could be from over fed'em or its a light burn,
its just a guessing game on my end without a good pic.
Head over to plant problems so you get a clear answer.
