Do marijuana plants require different nutrients as compared to other plants?

The short answer to this question is “No.”  All plant life on earth relies on the same general set of nutrients as composed from basic mineral elements found on this planet.

From the huge spectrum of elements in the Periodic Table, plant foods have 3 main ingredients that will be the mainstay of the garden, nitrogen (N), phosphorus (P), and potassium (K). These 3 ingredients are usually listed on the front label of the plant food in the order of N-P-K. A 20-20-20 plant food has a nitrogen level of 20%.

Secondary mineral nutrients are calcium, magnesium and sulphur. In trace quantities, you’ll find copper, boron, molybdenum, zinc, iron and manganese. These are typically found in much smaller (trace) quantities in a fertilizer or nutrient powder or solution.

The real essence of this question above can be better understood by knowing that while marijuana draws upon the same basic set of elemental mineral nutrients just like other plants on earth, its nutrient usage is unique in how and when it needs certain nutrients.  This is where the nutrient management skills of the grower come into crucial play. Depending on the stage of growth, different nutrients are needed at different times. For rooting and germination, levels of high P nutrients with less N/K are needed. During vegetative growth your plants need a lot of N.

  1. Yes the Marijuana plants just need the basic mineral elements as any other plant…and I think giving the Marijuana plants other special nutrients wouldn’t make any difference at all as Marijuana plants have grown well on their own without anyone giving them special nutrients.

  2. This should really be a given, it’s a plant just like any other! Maybe it requires different conditions but the food will be practically the same. I’m also curious, does strain of pot affect the nutrient management at all? Interesting article as usual, even though this was a bit more scientific :)

  3. No, they don’t – if they are just growing naturally, for the sake of providing oxygen and beautiful foliage. On the other hand, if you are growing for harvest, and especially for resale, you’d better pump those babies full of extra nutrients. Everything from “bud blast” to special flowering mixtures, to ensure the biggest, tightest, stankiest buds you can get.

    1. @Kat – Actually, if you look at the article “What happens if you grow your marijuana without using nutrients or if you give too much nutrients to your plants?”, the author brings up how too many nutrients can make it unhealthy. If you’re growing for resale, killing you plant definitely isn’t the way to go. The advice here sounds right for absolutely any plant.
