that is why we foliar spray right when the lights come on and we use a mix at 1/4 strength what the bottle recommends. Used on a variety of strains and growing mediums, never had a burning problem. Now if you use full strength and spray it in the middle of your lights on well... I dont use it on the hydro plants, only soil. I have a hard enough time keeping humidity down in the hydro room so foliar sprays are out of the question.
