MG potting Soil + Perlite?

Hey. Yet again another noob question from me lol. i tried to use the search option but was coming up with stuff not even related to perlite so here my question

I will be transplanting one of my plants in a min or 2 into a larger pot. and i was thinking of adding perlite into the MG potting soil and give that a shot on 1 plant.
Wondering how much of each i should be putting in and if this is a good/bad idea

Good idea. I do 2:1 but other people do diff things. 3:1 or 4:1 would be Kool. U want the soil to not be compact.

I'd say 3:1
