Thanks Weezard.
Now i realized i might be misunderstood. First two questions were connected. Somehow it ended up in the document like that.
"I will make a mix and add the totallmix in it or use that totallmix as it is." this what i meant actually. There will be other mix without it anyway. And using it as it is for one or two sounds much better. Since i used it for critical+'s i'm thinking to keep going with it to medium size pots and go to final size with some lighter substrate mix(will be decided later). Maybe this is too early to talk about. I'll re pot about a week or two weeks later but anyway talking is good, at least soon i will be able to attach photos here. Much comfortable
