definitely not rootbound at that young age ... are the cups dry all the way to the bottoms ? ... check and see if the cups are draining well, sometime water will sit in the bottom, and screw up the plant ... drooping can be caused by over-watering, or under-watering, only the grower can figure which situation he has ... and, you should not be adding ANY fertilizers in the first 2 weeks of growth ... then, fight the urge to fertilize after that, most problems are caused by too many additives, then trying to correct situations ... plant also is drawing nutrients from the soil, in addition to your additives, easy to step over the line (remember, it's a weed) ... good growing :thumbsup:
