I know the minimum recommended range is 50 however we the end of pool season coming I'm debating whether I should raise my CH. What are the cons of leaving it low?

Do you mean calcium or CYA (stabilizer)? There is no minimum for vinyl.

Confirm. If, by CH, you are referring to Calcium Hardness, there is no lower limit for vinyl. Plaster pools need to have calcium in the water to prevent calcium from leaching from the plaster, but there is no such need for vinyl.

I was going off of this link. pool-school/recommended_levels
