I recommended my buddy a silica supplement for his indoor grow, and hes asking me if when to use it, I vaugely remember hearing something a while ago or reading that it is not good to use silica supplements during the bud growth and maturation just in vegatative and stretch phase. could someone confirm that this is correct, and i had heard that if the nugs have alot of silica in them from using potassium silicate in mid/late flower that the buds burn harsh, can anyone confirm, thankyou VW
