Nutrient Lockout Symptoms

Nutrient Lockout Symptoms

When you notice your plants start showing discolored leaves or they begin to show poor growth, then these might be symptoms of a nutrient lockout.

A nutrient lockout can be simply put as plants’ inability to absorb or take in nutrients. These nutrients are available, but your plants can’t just take in these nutrients: thus, the occurrence of a nutrients lockout.

Nutrient lockouts occur frequently among hydroponic growers. Most times, newbies are usually frightened when this occurs because they might think they did something wrong. The important thing you should know is that both skilled and newbie growers experience a nutrients lockout. Also, making the right move to solving the problem is important to save your garden.

Nutrient Lockout Symptoms

Identifying nutrient lockout symptoms is very important. This is because if you mistakenly diagnose nutrient lockout to something else, you may do the exact opposite of what’s needed to be done making matters worse for your plants’ health.

Below are the symptoms you will observe when it comes to diagnosing nutrient lockout:

  • Discoloration of leaves
  • A few leaf burns.
  • Plants stunted growth.
  • Deformity of plant structure.

These symptoms are quite confusing because they are similar to the undernutrition of plants.  Some growers may not be conversant with these issues and they may think their plants need more nutrients. So they end up adding more nutrients.

This makes the situation worse because the plants’ environment is exposed to more salts or nutrients. This in turn affects the pH of the system causing more nutrient lockout.

Therefore, ensure you are aware of the right diagnoses to avoid nutrient overfeeding.

Causes Of Nutrient Lockout

The causes of nutrient lockout are:

  • Inappropriate pH Range: inappropriate pH range in soil or water can cause a nutrient lockout. pH levels should be maintained and kept between 5.5 and 6.5. It should also be measured routinely. Various types of minerals contained in nutrients can only be absorbed by your plant at exact pH ranges. When your pH levels do not meet some particular ranges, an adjustment will be needed quickly.
  • Build-up of Excess Minerals: when excess minerals in your reservoir build-up, it will cause a nutrient lockout. Always replace your nutrient solution every week or two weeks and keep your reservoir clean. Also, you can use clean water to rinse off excess nutrients from your plants’ roots.
  • Adding too many Nutrients: adding excess nutrients to your garden can also cause your plants not to be able to absorb nutrients. Nutrients contain salts and too much of it increases the pH of your garden causing the nutrient lockout. Ensure you follow instructions and apply the right amount of nutrients to your plant solution.
  • Inappropriate Mixing of Hydroponics Nutrients: when you don’t mix your hydroponics nutrients properly, it can cause the inability of the roots of your plants to absorb nutrients. Always read and follow instructions from your nutrient pack or bottle to mix appropriately.

Solutions Nutrient Lockout

After recognizing and confirming nutrient lockout symptoms in your hydroponics or soil, the next step is to solve the problem. Here’s how to fix nutrient lockout:

Flushing

To save your garden, the first thing to do is nutrient flushing. We recommend you clean your soil or growing medium by saturating it with fresh water. You can do this for 24 hours or so. Also, go ahead and empty your reservoir and rinse it well.

You can also make use of a special leaching agent to flush out excess nutrients that must have build up in your garden.

After successfully flushing your garden, allow the soil to dry. If you are making use of hydroponics, make sure you feed your plants with the correct amount of nutrients afterward.

How To Reduce Risk Of Nute Lockout

Just as it is important to identify and fix nutrient lockout, it is also crucial to reduce the risk of re-occurrence or running into one.

You can avoid the risk of a nutrient lockout by judiciously checking the pH level of your system. Also, when you want to change your nutrient solution, do so carefully by checking the pH level of your growing medium.

If you notice any changes in pH, flush your system when necessary. You should also ensure you don’t do flushing close to your crop harvesting time.

Bottom Line

The bottom line, nutrient lockout symptoms are common, especially in hydroponics. If you regularly take precautions in advance, you can avoid or reduce the risk of a nutrient lockout.

Monitoring pH levels, using the correct amount of nutrients, and doing routine flushing when necessary are all excellent practices in keeping your garden safe.
