It's Easy Bein' Cheesey

Seeds placed in Root Riot cubes on 1/8/2017 at 4pm and all three popped just before dawn on 1/10/2017. Left in the germination tray until 1/14/2017 and transplanted into 2 gal smart pots filled with Canna Coco and 25% perlite which will eventually be placed in a drip system. I still have a Dinafem Sour Diesel Auto in a root riot that has not sprouted. Seed appears swelled and split. Will give a few more days. Seedlings currently under 3 x 23w 6500k cfl on a workbench awaiting their final 4x4 room with a 600w MH/HPS to be ready. Just waiting for a couple fans to arrive. Upon advice, waiting to begin light nute feeding until cotyledon to start to yellow. This is my first seed grow and probably tackling way to much as I have another grow going thats currently in flowering that I started from clones. 1/16 pulled up Sour Diesel seed, seed swell up started to split and then stalled and hasn't popped in 8 days. Placed back in Root Riot and back into the nursery. I dropped a Fast Buds Girl Scout Cookies Auto to add to this grow. If the Sour Diesel actually sprouts I have room for up to 6 plants in my setup.
