The key to successful cannabis growing lies in proper plant nutrition. It's true that every environmental factor should be adequately laid down in order to maximize the outcome of your crop: air exchange, type of lighting, temperature, humidity, etc. However, it would be pointless to choose a complete and balanced range of fertilizers if you are not taking into account the pH of the nutrient solution, or in other words, the acidity or alkalinity level in the feed you are giving to your plants.
To ensure proper nutrient uptake through the plant's root system, each macro and micronutrient in the marijuana feed must be administered with regard to a particular acidity value (pH), otherwise the absorption won't be adequate. This factor is very important to make the most of the fertilizers and to prevent nutrient deficiencies and overfeeding problems, thus obtaining a bountiful harvest.
