I take a gallon of RO water in a sprayer with like 5-7 drops of original dawn soap and like 30ml or so of 91 percent rubbing alcohol. Can be up to 10% alcohol concentration but dont need it that strong. Spray plants throughly let sit for a minute or two then rinse leaves with fresh RO. Do this 2 times a week as maintenance if having issues, also do this in the evening or after lights are off as it could fry your plants in the light. Happy growing 💨
