*Whats wrong with my BCN?*

Just started with the dwc and my bcn diesel is having issues;

Lighting:
5 27w 6500k
3 45w 6500k
1 85w 6500k
1 85w 2700k

Nutrients:
Using this product called david's grow...the folks down at brew and grow said that its just about the same as the fox farms trio.

The bcn is about a week older than the other 2 (1 lowryder2, red diesel)

What do you guys think is the issue?
(also added in a couple pics of my plants outside)

there is no issue you have to let them grow!! Btw way too early to be using nutes

Unless it's a SUPER low amount. I generally use 100 ppm and up during week 1. They can grow a lot that first week with nutes!
