how to treat Calcium deficiency?

well, its the lights that make trouble for your Plant, its alot of high quality light that shines on the Girl.. she grows very dwarfed with short internnods, that say to me... To much light// to close Follow my thoughts away from to close its possibly to warm too Growing with high end LED changes the growingstyle Rise the Light, and delute your Nutrients, so the plant soaks more Pure water. Because she transpirates alot, water evaporates and nutrient remain in the leaf and burn it too..... if you use solution in regular strength. happy growing..
