What nutrients do plants get from soil?
The three most important macronutrients for plants are nitrogen, phosphorous, and potassium. These three nutrients make up the N-P-K ratio. Three essential secondary nutrients for plants are magnesium, sulfur, and calcium. All six of these nutrients are readily available in soil, but can be difficult for the plant to absorb, and thus we must feed our plants all of these nutrients.
If you use a nutrient-rich potting soil, like Fox Farm Happy Frog, your plant will have access to nutrition early on. But as you water the soil and your plants eat, these nutrients start to vanish, and before you know it, your plant has developed a deficiency.
This is why you need to be feeding liquid nutrients starting in veg, and through flower.
What are immobile soil nutrients?
Mobility of soil nutrients refers to their ability to be transported within the plant. Deficiencies of immobile nutrients appear first in new growth, since the plant was not able to send adequate amounts up the shoot. Mobile nutrients are the opposite, and you will notice deficiencies of these in older leaves.
Phosphorous, potassium, chlorine, and zinc are examples of mobile nutrients, whereas calcium, sulfur, boron, and copper are not. Knowing which nutrients are mobile will help you diagnose your deficiency.
