Does additional nutrition supplement really make a difference?

Im considering buying SuperVit and Phosphorous Plus but i'd like to know from someone with experience if these really make a difference in bud weight when its harvesting time.

Never used those brands, but phosphorus definately helps increase bud growth. it makes a huge difference

I already use hesi bloom complex 3-4-4, im not sure how high demand the plant has for phosphorous.
Would buying phosphorous plus increase my yield?
