NO,NO,NO! take the time to search for it! Blackstrap 1-2 TBS per gal. of water depending on size during budding. Now its said to not do much during the first 2wks and thats when I use 1TBS and I use 2TBS during mid weeks to load up on the carbs. You deff want to STOP using 2wks prior to harvest or your bud will be harsh and bitter tasting. I switch to apple juice for the last weeks.That way you end up with fat juicy sweet tasting ganga!!
