do not use sugar whoever told you this is retarded and does not grow. You can use unsulpher black strap molasses or products derived from it such as sweet,sugar daddy, carbo load,Sweet leaf and such. Add molasses at a ratio of 2 table spoons per gallon of water in hydro each res change. In soil use it every other watering no more then 3 times a week...what your after here is the carbohydrate which allow more nutrient intake and usage which increases resin out put which means sticker heavier buds. Dont forget to flush at end of grow
