what is the difference between these 2 soils?

im looking for soil for my next grow, i want the best stuff i can get really

heres the 2 biobizz soils that basementlighting have pls advice which one i should get, ill be growing auto ak47 indoors, with advance nutrients iguana juice.

BioBizz All-Mix Soil

BioBizz Light-Mix Soil

i think the light-mix is for people who want to mix stuff in them selves, but its more expensive than all-mix
