Problems at 4 weeks - Yellow leaves

[Bigal07]

Hi all,

New to this and have a theoretical problem with a grow. 4 weeks since the seed was planted and up until now been healthy looking, but now the bottom leaves are going yellow and dying. Where is it going wrong?

Conditions:
600w HPS lamp
Miracle Gro fertilized multi-purpose soil

Any advice much appreciated.
