3 QUESTIONS ABOUT FERTILIZER USE
The use of fertilizers is a subject that the owner of an indoor crop can not help but worry about. It is one of the items that help ensure a quality result, together with the care and dedication with the plantation. Being well informed about it is essential. And so we have gathered in this posts answers to three questions about the use of fertilizers.
WHEN SHOULD I START USING FERTILIZERS IN MY INDOOR CULTIVATION?
The use of fertilizers should start from the third or fourth week of plant life. This is an important care. Many may think that already in planting fertilizers should be applied. But no, before that, the plant needs water and light. When you start using fertilizers, the recommendation is always to start with low doses and gradually increase until reaching the dose indicated on the fertilizer label.
To help you understand when it is the right time to use fertilizers, check out the following tips:
>>From germination to the first three weeks of life: water and light;
>>From the third week: fertilizer rich in Nitrogen;
>>Supply the demands for other nutrients (Potassium-K, Phosphorus-P, Boron, Copper, Molybdenum, Iron, Manganese, Magnesium, etc);
>>From the sixth week: fertilizer rich in Potassium and Phosphorus;
>>During flowering, the need for Nitrogen gradually decreases and increases the need for Potassium, Phosphorus, and microelements. And attention, the excess of Nitrogen in the phase of flowering can stop the development of the flowers.
WHAT CRITERIA SHOULD I ADOPT TO BUY THE RIGHT FERTILIZER FOR MY CROP?
The most important are to identify the stage of development of the plants and, from there, to evaluate the main demands for nutrients of the plant. Each stage needs a nutrient (or a set of them) in specific, as indicated in the previous answer. Example: growth phase there is a higher demand for Nitrogen, flowering phase there is the greater need for phosphorus.
It is also important to ensure the supply of other nutrients, especially when the crop is hydroponic, aeroponic or with inert substrates should be careful at the time of purchase and choose a fertilizer rich in all nutrients.
CAN I ONLY USE ORGANIC FERTILIZERS OR DO I NEED TO SUPPLEMENT THEM WITH MINERAL FERTILIZERS TOO?
The recommended is always to use only a line of fertilizers, or mineral or organic. Use without criterion can easily cause overdosing, the popular overheat, and kill your plants. This is because the fertilizer contains a certain concentration of nutrients, specifically designed to meet the needs of the plant. If they are applied in excess they can cause the leaves to burn, the first overheat signal.
The decision of which and when to use them depends on the stage of the plant and also the needs that you identify for cultivation. Organic fertilizers, for example, help retain more water and make root growth more favorable. In addition, they also strengthen the development of microorganisms that are sources of nutrients for plants.
Mineral fertilizers, in turn, give the farmer greater control over a number of nutrients and an ally to fight pests. But for the use of mineral fertilizers requires greater attention so there is no error in the dosage. The risk of committing excesses increases.
