First grow palr yellow leaves???

Hey all my plants are around 6 weeks old and this week have started getting pale yellow leaves with a brown tip but are only the very bottom leaves. Im not sure exactly what the problem is but some advice would be greatly appreciated...

Grow medium- brunnings tomato and veg
Light- 6x 24w cfls
Water/feed cylcle- every 4-5 days
1/3rd nutes with water
Soil ph is around 6.0-6.5

Maybe a pic of whole plant will help. Those first few leaves on a plant don't last too long so pluck them off and see if it is spreading up.
