Hey! Got an auto ww x bb. She started turing yellow 1-2 in flower. Been watering her with only water till the last watering and i gave it: Canna terra flores , pk13/14 , cannazym and calmag. Should i keep using it? Couse i guess its just nutrient def? Sent from my iPhone using Grasscity Forum
Very possibly a lack of nitrogen. While it's true the plant needs less nitrogen during flowering, the element is still required. With nitrogen deficiency, the plant starts feeding on the older leaves to support new growth.
Alternate between a veg nutrient and flower nutrient for a few weeks. The plant has a significant lack of nitrogen
