Hi guys , i am also interested as someone i know purchased some of this soil also , but the professional + version ( different ? ) but it seems very loose and barky , is this ok or was this stuff designed to be mixed with a more soil/earthy product ? My friends plants have small leaf growth , redish stems and is alround growing slowly to the point where he is looking at changing soil ... How are your plants reacting ? Do you know if this soil ( canna terra pro + ) has the required npk nuts of are additives definatly needed
