Oh, so you haven't figured out what to feed them yet? My favourite, all-purpose fertilizer is General Hydroponics 3-part (Micro, grow, and bloom) which should be available at any large outlet. It's simple to use, and fairly pH neutral (i.e. when you mix it, you won't have to mess around too much with setting the pH). I had great success with it in the past using DWC.As for nutes? I'm trying to find something easy and simple to use. The LED light was about less than a 12" for the first weeks, but I moved them to about 2' to try to encourage some stretching.
But personally, I prefer chemicals proper (like Calcium Nitrate, Phosphates, Epsom salts, etc...) since I like to control the ppms in detail. But I wouldn't recommend that unless you are ready to sit down and do some number crunching and anal-retentive weighing (to the 100th of a gram).
As for light height, it seems a little high to me. Remember that you can consider the light like a point source--its "strength" will fall off at an inversely squared rate, so the power getting to the plants (if you went from 1 to 2 feet) would be 4x less approximately. Now it's not exactly that kind of ratio (due to the focus of the LEDs) but it is something to consider.
However, light height is not as much of an issue relative to the lack of food
So that should be a top priority, in my humble opinion. And don't take my word as gospel; go with whatever you are most comfortable and confident in.
Anyway, I wish you luck and hope you get everything settled. I want to see how this light performs in your hands
