Edges of leaf turning a lighter green?

[AutoV]

Problem: The edges of my five finger leaves are a light green. This problem is no where else on the plant and initially the edges was under the larger center leaf until I moved them a little bit and saw the edges.
Medium: Soil (Fox Farm Ocean Forest)
Feed: up until day 22 I've fed with just distilled water. Day 22 I fed the a liter and a half from a gallon jug of distilled water that was mixed with 1/4 teaspoon of fox farm grow big.
Strain: Blueberry Auto from speed seeds (ordered from single seed centre) started from seed
Climate: When lights are on tempertures sometime get as high as 83. When lights are off temperatures go down to 74-75. Humidity is around 40 when I havent watered. Humidity when watered is usually 65. Im using two 13w 6500k cfls for veg they're 2inches away from plant. Im growing one plant.
Additional Info: The cotyledons are yellowing . I don't check ph. I haven't had any problems up until now.

I think they look very healthy, they probably are just needing a little feed. How are they now?
