If you fed them the liquid or any another additive, flush immediately with properly ph'd water, as it's way too soon to be feeding them extra. There's already enough nutrients in the potting mix to last a month and a half or longer. The bronzing could be from too many nutrients, or too much Superthrive. (are you using any Superthrive or a similar additive?)
No i've not added anything at all just the potting soil and water, I transplanted into a bigger pot yesterday and lowered it a bit from the tubes when I came home today it looked kinda the same just a bit taller cause its further from the lights. I suppose its a good thing that its noticeably growing.
