Why Your Buds Are Light and Fluffy (And No — It’s Not Genetics)

Light and fluffy cannabis buds are rarely caused by genetics. Learn how LED lighting, VPD, nitrogen, temperature, and late-flowering mistakes affect bud density — and what to do step by step to grow dense, heavy flowers.

A Deficiency That Doesn’t Exist – How You Create Nutrient Problems Yourself

False nutrient deficiencies are a common mistake in cannabis cultivation. Learn what nutrient lockout really is, how pH, VPD, and temperature imitate deficiencies, and why adding fertilizer often makes the problem worse.

Cal-Mag: When It Is Needed — and When It Destroys a Grow (Truth, Myths and LED Traps)

Cal-Mag in cannabis growing without myths: when it is truly needed, when it harms plants, how LEDs and VPD affect calcium and magnesium uptake.

Why the Plant Does Not Absorb Nutrients: Transpiration, Roots and Nutrient Lockouts in Practice

Why cannabis plants do not absorb nutrients: transpiration, roots and nutrient lockouts explained step by step, with practical diagnosis and solutions.

Bloom Boosters – Do They Really Make a Difference in Cannabis Cultivation?

Bloom boosters – just another grow shop gimmick or the real key to fat, resinous buds? Find out how they work, what’s inside, and when it’s worth using them if you want your cannabis grow to produce premium yields.

Cal-Mag: shield or placebo?

More and more growers use Cal-Mag when growing under LEDs and with filtered water. But does every plant really need it? Find out when calcium and magnesium supplementation is a lifesaver and when it can do more harm than good.

Soil feeding plan for marijuana — from seedling to harvest, week by week

How to feed cannabis in soil: when plain water, when half-strength, when full; pH 6.3–6.8, a simple water–water–feed rhythm, how much water per pot and how not to overdo it.

When to Start and When to Stop Fertilizing?

When should you start fertilizing and when should you stop? This is one of the most common questions for new growers. Learn why seedlings don’t need full feeding yet, how nutrient demand gradually increases, and when it’s best to transition to bloom formulas and finally to flushing before harvest.
