I'd move the air pump out of the tent since you're going to supplement CO2. Leaves like CO2, roots like oxygen and the air pump will intake the CO2 and pump it into the DWC bucket/tote. I'd adjust the fans so that the seedlings gently sway (visibly) and you can add more force as the stems/trunks thicken.
When you do feed them keep an eye out for any sign of nutrient burn and be prepared to dilute the solution if needed. As beefxer said, young plants are tender and they won't use much nutrients at first.

The GFP is fucking amazing so far, and I haven't even received my lights yet! (They'll be here tomorrow).
I've been dabbling in the cannabis world for only 3 months but have already met more than a handful of unprofessional assholes, crooks or morons who take advantage of people in pain, in need, or who are just interested in cannabis in general and look up to these dishonest people for advice.
If I had known what I know now three months ago, I'd have done EVERYTHING differently. I wasted hundreds of dollars with bad merchants but now I have a trusted grow shop that provides A+, personalized customer service (that'd be Grower's House in my case... they have tier 4 UPS pricing for Canada and beat any grow shop we have here by at least 20% on every price, not to mention their selection is limitless) and light manufacturer I can trust, I can only look forward to the future without fear or stress now. And that has no price.
In my opinion, as far as transparency and professionalism is concerned, Cali Lightworks sets the bar and everyone is under it. As for the results, we'll have to wait and see.
If raising the light doesn't help, try lowering the temp a degree or so.
I've seen my share of assholes, children and morons in other grow forums too, we try to be more mature and respectful here.
Keep on keeping on...

The girls looks fantastic. I'm not sure whether it's because of the raised light or the fact roots are touching water now but the branches seem to have spaced out a lot to accommodate new grow sites. The transformation is obvious. They were so much more compact a yesterday or the day before.
How far is that light and what is your schedule? Typically we want tight internodes and stretching is often a sign of not enough light. It can be just due to genetics and we *know* you have enough w/sqft so, *perhaps*, the light is to far away?
FYI: I just looked up your genetics and it says: "Kali plants grow to a medium height with long internodes and medium-long fan leaves." It is mostly sativa so stretching isn't abnormal.
