found within the soil but sometimes not all of them are there. The

and S (sulphur). CaMgS for short. There are also seven more
micronutrients. These are as follows: iron, boron, chlorine,
manganese, copper, zinc, and molybdenum.
These micronutrients are not extremely important for good
plant health, but the secondary nutrients and Primary nutrients are.
Check your bag to see if it has some secondary nutrients.
Sometimes a Ca, Mg, or S deficiency in the soil may cause
growing problems for your plant. If the soil is lacking one of these
factors your plant may start to display a nutrient deficiency. Mg
problems are common. To correct this feed your plant a 1/3 of a spoon
full of Epsom salts per 3 gallons of water every 3 - 4 weeks.
