Quite true that clones can't make any use of nutes until they have roots, but in rockwool cubes you don't see the roots from the very instant nodes have formed. You see them a couple of days later. Putting a weak nute soln (~400ppm, 5ml Canna Vega "A" & "B" in 10L water, corrected to pH 5.5) on the clones means they can get at the nutes a couple of days before you see them out of the bottom of the RW cube.
