For soil, use the early vegetative rate (5 ml\/gal stock solution) and apply when the top inch is dry.

During weeks 7–8, use 10 ml\/gal of both Grow Green and Blossom Green simultaneously. Then drop Grow Green to 5 ml\/gal in early bloom while increasing Blossom Green to 15 ml\/gal. By peak bloom (week 11+), Grow Green drops to 0 and Blossom Green carries the program. This gradual shift prevents the nitrogen crash and yellowing that often occurs with abrupt formula changes.
