I start mollasses at 4 weeks flowering,1 tbl spoon per gal water, twice a week, increase times u feed until ur givin plants moll every other watering in 8-9 weeks of flowering. Ratio stays the same. Heat moll bottle with hot water, put tbl spoon moll into cup of hot water, add tea to water bucket. I grow soil 3 gal buckets. Dont believe this works hydro grows, u can use up to harvest, no chems to flush all natural.
