granted certain strains vary in the exact requirement, but is there a rough ratio?

i ask because i was speaking to someone who said cactus food was an extremely good fertiliser as the delivery patterns of nutrients is identical.

anyone got any thoughts on the cactus food? some rough pointers with nutes would be appreciated, when to start and when to change to what ones?
