Some ripeners give more than others, you'd have to do reaearch , kushie kush is designed to replace both big bud and overdrive, its npk is 1-3-8
Some should be coupled together, such as floraliscious plus and dry koolbloom. You have to do some reaserch but a lot of ripeners cover more than one bloom enhancement nute alone. I don't claim to know why or which ones but I know kushie kush can replace two of them alone(big bud and overdrive)
Dry koolbloom is to be used at the end of the harvest because the steroids are only found in the liquid form which says to use during week 1-6. Confusing shit.
That said, look into terpinator, I've used it before and all by itself and increased my harvest by 30% and quality by a buttload by using it at 130% recommended dose.
