look like bigger plant is suffering from magnesium deficiency, and smaller plant is probably rootbound and suffering from nitrogen deficiency. https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

Hongo mildiu?
Hace unos días, las primeras hojas presentaron zonas con necrosis, y día a día avanzó. Será por el riego foliar con ? Por el viento directo del fan? O es un hongo mildiu? Un día la H.R llego al 80 90%, el crecimiento avanza pero muy lento, el sustrato parece tardar en secarse.

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.
I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?

Late Flowering Stage Deficiency or Nutrient Burn
I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.
