What Is A Deficiency Of Nutrients?

A deficiency of nutrients occurs when there are not enough of certain elements or minerals in the diet. These deficiencies may cause physical changes such as growth retardation, lethargy, loss of appetite, and even death. Plants require a wide range of nutrients in order to grow properly. Too little will result in stunted growth and poor quality fruit production; too much will lead to disease problems.

The most common types of nutrient deficiencies are iron, zinc, calcium, magnesium, manganese and copper. Iron deficiency is one of the most dangerous because it leads to muscle weakness and a lack of energy. Zinc deficiency results in hair loss and brittle nails. Calcium deficiency can lead to kidney stones and bone deformities. Magnesium deficiency can affect the nervous system causing depression, hallucinations or seizures.

Copper deficiency can cause high blood pressure, heart failure and cancer.

How To Fix Yellow Leaf Problems On Plants?

In order to correct yellow leaf problems on plants, you need to provide your plants with adequate amounts of all the nutrients they require. You do this by feeding them at regular intervals during the growing season. If you feed your plants too infrequently, they won’t get enough nutrition and will suffer from a deficiency. If you over-feed them, the excess nutrients will be wasted and can cause problems of their own.

The ‘secret’ to providing all the nutrients your plants need to produce healthy fruit is to get a complete fertilizer that contains all the major and minor elements required by plants. Most quality fertilizers have these nutrients listed on the back, so you can check to see if they contain what your plant needs.

When to use a complete fertilizer: use a complete fertilizer throughout the entire life cycle of your plant, from seedling to harvest.

When NOT to use a complete fertilizer: you don’t need to use a complete fertilizer during the first weeks after germination as long as you are using a top quality germinating mix that contains all the nutrients required for healthy growth.

The most common form of fertilizers are liquids, but sometimes powders or blocks are more convenient. Most liquid fertilizers are divided into thirds for each watering, but you can also use a calculator to measure out the proper amount for your situation.

Growers have different preferences for when to feed their plants. The three main approaches are: Every day (also called “foliar feeding”), every other day, and once a week (sometimes also called “deep feeding”). When you feed your plant is just as important as how much you feed it. Liquid fertilizers are water-soluble and your plant will suck them up almost immediately, so you get results quickly. Many growers use liquid feed every day or every other day because it gives the plant a little boost in between the last feeding and harvest time.

Combined with the right techniques and the other tips found on this site, proper feeding is important to getting big buds.
