generally ya that sounds alright, i would add about 10-20% perlite 1/10-1/5 maybe even a 1/4 of ur mix be perlite.. add some dolmite lime or crush seashell to help balance the PH, and if u can add like a 1/4 sphagum peat. (i dont know in what exact amounts) but since i brought it to attention im sure someone with more experience can tell u how much...

other than that, if ur confident in that mixture, try 1 out, if it grows well in 3 weeks time u should be okay for others.
