There’s nothing inherently wrong with Miracle-Gro nutrients, and if you’re willing to learn about nutrients, you can use the various different formulas and get a cannabis plant to grow. For example if you’re using regular soil, you could use the standard Miracle-Gro formula for vegetative, and their “bloom” version for the cannabis flowering stage.
Do not use “Miracle-Gro” soil or any soil that has “extended release” nutrients for growing cannabis. These types of soil will continue to release nitrogen to your plant roots for up to 6 months. This can cause deficiencies or burn your cannabis plants in the flowering/budding stage, reducing your overall yields. I have seen growers successively grow cannabis in Miracle Gro, but many of them struggled with nutrient problems in the flowering stage (like the following) even though plants were healthy throughout the vegetative stage.
Miracle-Gro Slow Release Soil is Not Suited to Growing Marijuana!
The biggest problem with the standard Miracle-Gro nutrient formula is that it’s one formula for the entirety of the plant’s life cycle. Even if the standard Miracle-Gro plant food is decent for the first stage of your plant’s growth, it won’t be good for the budding/flowering phase. The ratio of nutrients your plants need changes drastically between seedling and full flower. Marijuana grows best with a nutrient system that accommodates their changing nutrient needs.
Important: Do not use “Miracle Gro” soil or any soil that has “extended release” nutrients. These types of soil will continue to release nitrogen to your plant roots for up to 6 months. This can burn your cannabis plants in the flowering/budding stage and reduce your overall yields.
Avoid Miracle-Gro Soil for Growing Weed!
What’s worse than the standard Miracle-Gro nutrients is the original Miracle-Gro soil. Standard Miracle-Gro soil has “time-released” nutrients which contain high levels of nitrogen. While this formula will work okay in the cannabis vegetative stage (the first stage of life), the nutrients will continue to be slowly released throughout the plant’s life including during the cannabis flowering stage, which is not good.
Standard Miracle Gro nutrients contain too much nitrogen and not enough of other nutrients for your cannabis flowering stage, and as a result of the time-released nutrients, you will notice that your leaves in the flowering stage will get nutrient burn and your buds just won’t grow as big as they could. Learn what you can do to make sure buds grow as big as possible!
Many of us have grown up seeing Miracle-Gro being used in our homes, so we know that it works for ‘regular houseplants’. Cannabis is just a tough weed, so Miracle-Gro should be great for it, right?
No, I wouldn’t recommend using Miracle-Gro to grow marijuana, or anything else. Not only is it derived from chemicals formulated in a laboratory, that laboratory happens to be the same one that brought us Monsanto, Scott’s, Roundup, Ortho and just about any other toxic chemical sludge they can derive. These are the same loathsome people genetically modifying and patenting seeds. Plants don’t need these poisons and neither does our environment. A Google search is all you need to discover the numerous crimes against humanity and our planet committed by these companies.
Instead, get yourself some nutrients made from natural ingredients such as kelp (seaweed), bat and seabird guanos, liquid fish or any of the other plentiful ways to feed your plants a proper diet of easily accessible food. The closer we get back to nature, the better our pot will taste and burn, and the planet will be much better off as well.
