Blue Dream by Humboldt Seeds, 300 W LED

As you can see, the one seedling I started in FFOF instead of the Black Gold was significantly larger than the others... I transplanted another into the FF just to see if it would make a difference, but it was probably too early to transplant into a container this large. The third seedling showed significant yellowing of leaves which I'm pretty sure what light-stress, as it was in the black gold mix...
