First Grow

First serious attempt at a grow. Mostly doing this to help keep a track of what I'm doing. Advice is welcome. Using a coco coir mixed with some organic potting soil, worm castings and lots of perlite. Under 2x 200W (actual draw) full spectrum LEDs and 200W CFL. Pics are 7 to 10 days from germination. They stretched a lot after the first couple of days after sprouting so just repotted into final pots asap. Bit of slow grow as my basement is still a bit chilly from winter, but trying my best to keep the temps up. Watering with a light mix of General Hydroponics 3 part at less than 1/4 strength for seedlings as per bottle directions plus a bit of misting the top of the coco mux to keep it damp.
