I'm going to second that recommendation. you don't get many duds when you grow premium genetics, and the seeds are too expensive to waste! Plus, I'm not convinced that you can tell which plant is going to be bigger when they're just seedlings.
Regarding the Molasses, don't put it in the reservoir as it is likely to clog up the valves. I would mix a spoonful with a quarter cup of water and then pour that right into the tray.
