Different deficiencies can have different outcomes on your plant and its health. It is important to remember when diagnosing a nutrient deficiency that you check and explore ALL elements of the plant/environment. Usually a nutrient deficiency is caused by another problem within the growing environment. It could be unhealthy roots or unstable pH, which surprisingly plays a critical role in nutrient uptake.

When you notice a nutrient deficiency, firstly check your plants roots. Are they nice and white? Or are they turning brown? Nice and white, the problem is clearly something else so keep investigating. If your roots are turning brown then your problem is in the root zone which will most likely be Pythium (root rot) which you can treat, we have a few products to help you with that. Make sure you check your pH, your EC/CF and the temperature/humidity in your growing environment. PH is crucial for nutrient uptake and too much nutrient adversely affects pH so accurately controlling both go hand in hand.

Here is a list of the more common nutrient deficiencies and their symptoms:
-Nitrogen: A nitrogen deficiency is recognisable through yellowing of the leaves, stunted leaf growth, and older leaves falling off the plant. 
-Phosphorous: In the early stages of the plants life, it will appear a dark blue/green shade. Plant growth and shoot development can be stunted. Leaves can curl and die, and have purple discolouration spots.
-Potassium: A potassium deficiency will have leaf curling, leaf yellowing, stunted plant growth, edges of the leaves turning rusty brown, and flowers failing to develop.
-Magnesium: A magnesium deficiency can be pin-pointed by rusty spots appearing on leaves, particularly older leaves. As the deficiency becomes worse, the spot numbers and size will increase.
-Calcium: With a calcium deficiency leaves will develop yellow/brown spots that grow bigger as the problem becomes worse. The plants growth will be stunted and the leaves will fail to fully expand. Usually younger leaves will start to yellow first.

There are many different products you can use to balance out a nutrient deficiency, The most common cause of nutrient deficiency is actually a build-up of nutrient salts, so before you go adding more nutrient ALWAYS flush first with pH adjusted water, it is recommended to test the EC/CF of the runoff and continue to flush until your EC/CF drops close to whatever your water EC/CF equals from the tap. It is always good practice to do a flush a few times during your growth and flowering phase to avoid a build-up because by the time you see the effects of a deficiency it will take quite some time for your plants to bounce back therefore effecting your harvest potential. For those of you with a hydroponic set up please dump your nutrient tank once a week rather than just topping up the EC/CF value with nutrient this will help avoid a raft of issues that can arise including deficiencies!! Every growing environment is different so we strongly recommended visiting, or calling, your nearest Hyalite store where our staff can help you pick the best product for your individual needs. We can also help you get the tools needed to monitor your pH, EC and keep your roots in tip-top shape so you can avoid nutrient deficiencies and enjoy a bountiful harvest.
