hey sap,

maybe you're just over anticipating. i use jump start too, both for cloning as well as part of the regular feeding schedule, especially at the plant's infant stages. the kelp has gotta do the plant some good. i use a bubble cloner too, and i've noticed that some clones grow a singularly long root or 2, while the rest lag behind. once i see that extending root i transplant to a system with higher concentrations of nutes. i figure this allows the rest of the roots to catch up more speedily than they would if left in the cloner. so far so good, they usually explode in growth after this. good luck.
