It seems that adding even a weak amt of veg nutes to the clone watering soln was in fact slowing them down. Now I'm just using pH 5.5-5.8 water on the clones until they have a good spray of roots, when they get chucked in the flowering area. Back to reliably seeing first roots out of the cubes in 7 days.
