Chemicals needed for growing weed

As a cannabis grower, your goal is to give your plants the right amount of nutrients at the right time. There are two main life stages for cannabis plants (vegetative stage and flowering stage). Each stage has different nutrient requirements. Luckily, many nutrient companies make great products even though they’re all using different formulas and techniques. Here’s how they differ:

Chemical Nutrients (including synthetic and mineral-based nutrients)

What’s the Best NPK Ratio for Cannabis Nutrients?

This plant was grown using the House & Garden Line-up (A+B as base nutrients, plus the supplements Roots Excelurator, Algen Extract, Bud XL, and shooting powder)

Cannabis needs different amounts of essential macros depending on the stage of development. Nitrogen is needed in higher quantities during the vegetative and bud-forming stages than during the flowering stage.

No matter what source, boron (B), manganese (Mn), zinc (Zn), copper (Cu), iron (Fe), and molybdenum (Mo) are always listed as essential micronutrients. Like the other essential nutrients, all micronutrients either have a unique function or serve to assist in the functions and processes of the other nutrients.

Essential Micronutrients
The number of micronutrients listed as essential can vary based on the source. Like secondary nutrients, it is somewhat a matter of classification as some list the secondary nutrients as micronutrients. Either way, they represent minerals and elements that are not as abundantly available on Earth and as such are not needed in very high amounts by cannabis plants, but are still necessary.

They do, however, need to be in a significantly higher quantity than the micronutrients, so they are separated here. The essential secondary nutrients are magnesium (Mg), calcium (Ca), and sulfur (S). These nutrients are often unavailable to cannabis if proper pH levels are not maintained (more on that later).

What does this have to do with the essential nutrients needed for growing cannabis? Nutrients may well be present in sufficient amounts to support robust growth and plant function, but they can be locked out or otherwise made unavailable to the plant. The ideal pH range to try to maintain for cannabis is generally accepted to be in the 6.0 to 6.5 range, with some variation depending on media selected. To determine pH, make sure to perform a soil analysis.
