Help Please.....pics

This plant is 22 days old and is beginning to yellow on the lower leaves. I'm using FF ocean forest and I ph my water to 6.4 every time. The cotyledons yellowed early on this plant so I used a 1/4 strength dose of grow big at the last watering seven days ago. Any advice would be greatly appreciated.

thats no problem, the first two true leavs will yellow every time, just cut them off after they have compleatly yellowed, whats happening is all the nitrogine that was once in those leavs is now moveing to a differant part of the plant leaveing them yellow.

That plant sure is looking nice, and will probably look better with them gone.

Does this mean that it could use more N?
