cotyledons turning yellow?

[sheist]

i'm seeing shades of yellow forming along the tip of my cotyledons.. any cause for concern?
its day 8, and my seedling is less than an inch tall, on 24/7 light from a 24w cfl.... it just started developing a root..

these are not true leaves, but provide the plant with nutrients at this early stage. They will turn yellow and die as the plant uses up the nutrients, this is quiet normal and nothing to worry about.
