Day 40 Slight yellowing on one girl...

[Traceofvenom]

I am using 5 gal smart pots. My soil mix from the start is:

Soil (Base Mix)
1.5 cubic ft of FoxFarm Ocean Forest
1 cubit feet of FoxFarm Light Warrior
1 cubic feet of Earth worm castings
1/3 cubit feet of Sphagnum Peet Moss

The soil base is very light and airy

I amended the soil with:
2 cups Botanicare Pure organic plant food (bloom)
1/2 cup Gypsum

I am feeding them the Earth Juice line just 2 part Grow and bloom. I also give them Maxicrops Liquid Seaweed and a touch of Protekt Silicon.

I am at day 40 flower and this particular one seems to be getting more yellow than the others on the upper growth. Nothing to crazy but just wondering if I need to make any changes and wanted to get some opinions. The first pic is the one in question then the others are just pictures of the overall grow. These strains have a harvest window from
55 to 70 days.

Thanks in advance I really appreciate it!

Would be better if you had pics in normal lighting....
