first time canna terra professional plus

Hey guys i bough this canna terra professional plus soil for my next autos grow, do you guys think I should mix with more perlite? and if yes what %

Also I saw in some topics that the ph of this soil is a bit controversial, what exactly ph should I water on it?

Thanks for your time guys!

IMO Add 25% perlite add more 30% if you intend to feed your own nutes later

aim your Ph pen at 6.5 the closer the better

good luck

What ph did you use in the end?
