@FoxyLoxy, You shouldn't need any nutrients added to a potting soil although some growers amend the soil with compost teas later in growth and flower. It is more of an Organic way to grow and there is plenty of reading on those subjects available.
Also, your claims to "deficiency ridden problems" could easily be attributed to environment and not lack of nutrients in the soil/medium. Cannabis is hardy and will normally survive but the end results suffer greatly...... Until you are fixed on a medium, nutrient line and ability to properly control your climate (air movement/temp/RHumidity) you will always notice issues and people will comment their idea of what your issues are sending you in all directions.....mostly as a nutrient deficiency (when usually its a PH issue causing the plant to lock out nutrient uptakes).
Unfortunately there is no way for anyone to read a diary and tell you exactly what your issues are 100%...but you will learn over the next year what they are and exactly how to fix them through trial and error and help from other growers....Just dont kill stuff :D:D:D
