With a good PH meter and some good quality nutes and taking the simple advice from the veterens on this forum you cant go wrong unless you are a total retard. Growing soiless is easy as taking candy from a baby just follow the simple rules and you will reep the rewards!

I use the Milwaukie SM802 meter and 3 part Advanced Nutrients with Cal Mag + for the veg then kick in some Big Bud for flower stage then flush with Flora Kleen

Smooth Sailing no brainer process!

Just my 2 cents

Peace
