The higher the CO2, the higher the nutes you can do. On my 1450 ppm CO2 in budding stage with carbohydrates causing plants to run through nutes in hyperdrive so fast the roots can handle 15-35-65. If CO2 goes out, everything dead of root burn with 5 hours. But I may leave last 2 plants to stress to max to force hermi for 50/50 femenized seeds & bring in a female to pollinate for 100% femized on that plant. Stress is best way to get seeds & you cannot stress a plant more than forcing it a month past it's ultimate life span.
