DreamITanswered grow question 5y ago Hello, it could be a nitrogen deficiency, Try to have a look at the link https://growdiaries.com/journal/cannabis-nutrient-deficiencies-guide or here https://www.growweedeasy.com/cannabis-plant-problems / nitrogen-deficiency. If you are fertilizing but don't notice any differences, start by checking the ph of the wastewater, maybe it's out of bounds :)
