Calcium
Calcium helps with cell development and cell growth. When readily available, calcium helps build strong cell walls and root walls. This helps in strengthening your plant and defending itself against pests and diseases. Most soils contain calcium to some capacity. However, soilless mediums, acidic soils and hydroponic gardens can be deficient.
Magnesium
Magnesium deficiencies are hard to spot because it takes at least a month for symptoms to appear. When deficiencies do appear, rust spots generally show up in older leafs. Your leafs also tend to curl and fall off. Magnesium deficient plants also look weak, sick and stunted.
