Flipped my girl to 12/12 ten days ago. Plant appears to be healthy and stretching good however I keep getting discolored leaves that die and fall off. Is it normal or am I looking at a deficiency here. Pics are what the leaves look like when they fall off. Other pic is the plant they are falling from. Using happy frog soil. Grow room between 18-23 C RH around 40-45 using dyna grow/flower nutes with cal mag and snowstorm ultra as a supplement
