Can anybody help?

So I’m almost two weeks into flower and I feel like my girls are a little pale. I’m feeding with emerald harvest nutrients every other watering. My ph is 6.4, I did a couple of slurry test and did an average. I’m growing in nectar of the gods #4 soil. Temp is 75ish in the day and 65 at night. Humidity is 51%

This has been happening every time I switch to flower

add a little bit more nitrogen and taper off a little later in flower

Get your temperature over 80. At least 80. I don’t see anything to be concerned about in those pictures.
