Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Iron deficiency?This A.M I treated her with a cal-mag mix due to yellow leaves. Today the leaf showing symptoms "tacoed" a little bit and the tip curled upwards. Same symptom on a few other leaves but only on the tips. Iron deficiency perhaps? PH'd soil on 3 spots: 6.6, 6.18, 6.3. What to do????

Leaf Discolouration I notice some leaves developing this yellow discoloration on the older growth, usually closer to the central stalk than the outside. The green gradually shifts to yellow going from mid leaf outward to the tip. I'm hoping it's just lack of sunlight from the dense foliage. Ideas?

Yellow leaves Started seeing new leaves turning yellow at the edges on this BCN Critical Auto. I think it's a calcium deficiency based on my research. Would love to get a second opinion and some tips, if possible. Many thanks.
