im growing two northern lights under a 100 watt diamond series led. Using fox farm ocean forest soil. Let them veg for five weeks then switched 12/12. I’m just over four weeks in and have been losing my bottom fan leaves. I bought two containers of nightcrawlers and put the castings, one in each pot, around them. Topped off with about an inch more fresh ff soil. I was hoping this would ease any deficiencies. I’m going for quality of taste over quantity of end product. I’m still fairly new to this but how serious is the deficiency and how will it affect quality and yield? Any and all info is greatly appreciated.
