Apparently Jacks has a Bloom feed & a Bloom Pro feed and they both have the exact same NPK of 10-30-20

So does anyone know what the difference is? This website specifically notifies you they are different products.

Are these supposed to be ran towards the end of flower as a PK Booster on top of Jacks 321 recipe?
