i was watching you tube the other night and came across a vid from japan showing the use of iodized acidic water ph 2.5-3.5 i think used for foliar disease control. they used a machine to separated their water, one side acidic water the other alkaline water, they used the alkaline for regular watering and the acidic for foliar disease control? they say since the water is so acidic no bacteria or fungi could grow on leaf surface killing any disease present. my thought is that couldn't be good for the good guys present or desired ph levels for the plant it self? anybody heard of this before?
