yup RO and distilled can caseu problems, however when problems are solved you have better controll over your hydro systems, or soil grows. also salt bulid up and flushing is less of a issue, final flushing can be done in a week in coco everytime, and the same with hydro, and still reach optimum flush in the plant. however I realy think that money spent on a RO filter system could be better spent on a omni water molicule system. making the water and nutrients more availabe to the plant. (I also dont know and have never used much of the omni but I understand that making water an nutrient more available to the plant is better than more filtered water)
MadSativa Reviewed by MadSativa on . Reverse Osmosis can cause issues I am learning over the last 2 years that RO water is not a good idea for our plants. RO is so efficient that it removes good nutrients like calcium, magnesium, iron, potassium, zinc, and many others. Plants become micronutrient defficient. I now feel that if a person uses RO water they need to replace ALL micronutrients. And because mixes and ferts expect those micronutrients to be present in the water supply, the plants can show many different forms of stress, the most prevelent one Rating: 5
