Is this enough perlite to add to my Biobizz?

Hey guys!

Hope all is well with everyone! I’m starting my grow in a few days and I just got a 50L bag of Biobizz Light mix for a 3 auto grow in 5 gal fabric pots. I wanted to add perlite but I was unsure on the amount needed. A 50L bag of Biobizz is about 13 gallons so I wanted to make up the 2 gal difference with perlite. Would a 2 cu ft bag be enough?
