Rooting powders tend to have VERY high concentrations of synthetic auxins, and can damage all but the the sturdiest of orchids. They are really intended for use on cuttings of woody plants.
Superthrive - if it is fresh - also contains synthetic auxins, so adding more increases the probability of deformity and stunting of growth. Don't forget, the weed killer 2,4-D is an auxin that excites plant growth to the point of death.
KelpMax has natural auxins, but is also loaded with polyamines that, together, stimulates root growth more than reasonable doses of auxins can alone, and without the risk of damage or deformity.
