i use big bud for week 2-6 and overdrive 7and 8 and flush week 9 and 10 sativa.. so if your looking to be done in 8-9 weeks use the monster for 2 or 3 weeks before you flush and flush for 1 or 2 weeks.if you have more then 1 plant you can experiment to see what works best just keep you ppm the same . i use 200ppm big bud and then nutes to get my final ppm to 800-1000
