Why? You have magnesium deficiency. People have offered help. I don't understand. I won't recommend
FFOF because I can make soil 20x fertile with my eyes closed but I would definitely recommend a change if you want to actually smoke what you grow.
Roots, that's a lotta nada...convincing LOS growers they need to add nitrogen since forever...
Let me tell you how they get nitrogen for synthetic fertilizer...they use high amounts of heat to extract it from thin air...yep the air is roughly 70% nitrogen. Nitrogen fixing bacteria will grab it right out of the air.
1 bag of alfalfa would have done more justice...
