I have always used 2 tablsppons per gallon once a week from about 2 weeks old in soil.You start it early as the plant uses the sugars and carbs to help process food and produce more resin.I like to use a 1 gallin of warm water then add the needed amount of molasses then mix it til its well disolved will look like watered down coffee and kinda stinks.Then mix that with the room temp regular water stir and then water.It works the same with fllod tables but dont use it with aero buy sweet, sweet leaf or Humbodlt counties Gravity.
