In the first week of the last 3 weeks of flowering, reduce the E.C. of your base nutrient to 1.2 and then add Top Shooter at a rate of 1.4ml/Litre. Adjust pH as normal. For the last 2 weeks of flowering, again use a base nutrient solution with an E.C. of 1.2 but add Top Shooter at a rate of 2.0ml/Litre and then adjust pH to the required level.
