Over 3 decades experience selling cannabis seeds has shown Dutch Passion that perhaps the most common error by cannabis growers is over/under feeding their plants with mineral nutrients. The result is restricted growth with under feeding or stunted growth (with ‘burnt’ leaf tips) when over-feeding.
In both cases harvest size and quality are reduced. If that sounds like a familiar issue in your grow room then you may be relieved to know that slow-release organic nutrients such as those from the market leader (BioTabs) are the easiest way to keep your plants in the nutrient ‘sweet-spot’ (without over or under feeding).
Many growers have seen their grow room results completely transformed once they replaced their traditional nutrient regime with slow release organic BioTabs.
