The nutrient industry makes more money when you’re confused. Let’s fix that.
Some of the most persistent myths in cannabis cultivation exist because they sell products. More bottles, more additives, more complicated schedules with more line items on the feed chart. Complexity is not the same as effectiveness, and for too long growers have been paying for the former while hoping for the latter.
We are going through five of the most common ones, one per slide.
Myth 1: More nutrients equals more yield. The evidence is consistently in the opposite direction. Overfeeding causes nutrient toxicity, salt buildup, and osmotic stress that actually reduces plant performance. Most home growers who switch from maximum strength to 70-80% strength see better results, not worse.
Myth 2: Expensive nutrients grow better plants. Price and effectiveness have very little correlation in this industry. What matters is the chemistry of what is in the bottle and whether the ratios match your plant’s actual needs.
Myth 3: Flushing at the end of your grow improves flavor. This is one of the most debated topics and the research does not support the idea that a harvest flush changes final product quality. What matters is the feed profile over the entire grow.
Myth 4: pH does not matter in soil. It absolutely does. Soil buffers pH better than coco or hydro, but drift still happens. If your root zone drops below 6.0 or climbs above 7.0, you will see lockout regardless of what nutrients you are running.
Myth 5: Cal-Mag is optional. Not in coco. Coco coir has a high affinity for calcium and magnesium, stripping them from your nutrient solution before roots absorb them. In coco, CalMag is not a supplement. It is baseline.
Save this for the grower in your life who needs to hear it.
