Supersoil mix

Pretty good, but I would halve the amount of dolomite lime and bio char. Too much dolomite will cause huge problems with (high) pH and once added is very, very difficult to reverse. Far easier to under dose and then top up if required. Maybe double the guano. Molasses does nothing in my experiments/experience.....far better to use kelp extract/tonic, this will "activate" your soil mix and add potassium and many other stimulants. Letting it sit for 3-8 weeks would be better than just one week........(3 weeks would be my minimum). Adding both volcanic rock dust and bone meal would also be good. Alfalfa meal is another great additive. Good luck and happy growing!
