CKS Auto White Widow - First grow

I started 2 seeds by soaking them in a glass of water for 14 hours, then transferring them to a paper towel - both had 1/4in tap roots. I then put them straight into a 3gal and 5gal fabric pot. They took roughly 48 hours to sprout. My wife attempted to de-shell the 3gal and ended up slicing one of the Cotyledon's straight down the middle. Its now yellowing pretty bad and its not going to make it. I started another seed by soaking for 14 hours, and putting it in a jiffy pellet (wanted to try another method). Soil: 1lb Natures Living Soil, mixed with Fox Farm Ocean Forest in bottom 1/3, then filled with FFOF. Took 1 cup out of middle and mixed 50/50 FFOF/Light Warrior Temp: 70-76 RH: 55-65% EDIT: Started #3 because neither of the first two grew properly. The first one was given away to someone to nurse because the leaf was split trying to de-helmet her. She is still a runt at day 24. The second was put directly into some light warrior and Ocean Forest - seems it was too much nitrogen.
