Taking a look into optimal pH levels when growing cannabis and their associated nutrient availability. The first thing any cannabis cultivator needs to check when growing cannabis for optimal results, is the pH levels of the medium being usedand of course the nutrients/water being feed to them.
The cannabis plant thrives in slightly acidic pH levels. Soil growers should aim for a pH range of 6 - 6.7 , Where as Hydro growers should go slightly
lower which helps prevent pythium and other forms of root rot keeping that in mind the ideal range for a hydro grower is between 5.6 - 6.2 the only exception to this in a hydro ponic medium is in the case of coco where the ph should be closer to the range used in soil grows however not allowed to fluctuate past 6.5
