Flower start 5/2.5/10 this is setup as G/M/B. If you are using any flowering adds like Koolbloom then keep the mix the same and add Koolbloom at 3/4 what package says. If not using an add then after 2nd or 3rd week of flower take bloom to 15.
thank you. the guidelines are meant for pro growers who know how to compensate. even still you shouldnt feed bloom formula in seedling stage as its unused portions will build up and cause problems.
