I think it’s 6
These six essential nutrients are nitrogen, phosphorus, potassium, magnesium, sulfur and calcium. The cool thing about these key nutrients is that they help create new cells, which then organize into plant tissue. Without these nutrients, growth and survival would not occur.

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
