Im new to this and have been following a recipe to build my own soil which I will be transferring my seedlings to after about six weeks veg. (In three weeks time) The recipe I used is 1:1:1 ratio of sphagnum, peat, and compost (about 90 litres total) with ammendments: 6 cups rock mineral dust 3 cups gypsum powder 6 cups organic sheep manure pellets 3 cups kelp meal The soil has been cooking for about 4 weeks now and reading a pH of 5. What are my best options for getting it closer to best range ie 6? I have dolomite lime I could use but am weary about the amount I need to use per cubic centimetre. Any suggestions greatly appreciated!
