Another thing to consider:
Using distilled water is like growing in coir. There is zero total dissolved solids (TDS) in distilled water just like there is zero nutrition in coir.
That means no Boron, Manganese, Molybdenum, Copper, Zinc, Chloride, Iron, Calcium, Magnesium, Sulfur, Nitrogen, Phosphorus, or Potassium in distilled water or even low TDS RO water for that matter. You have to provide every primary, secondary, and micronutrient. Get it wrong and the plant will suffer.
If you use dechlorinated tap water (pH’ed) you don’t have to concern yourself with all the trace micronutrients because they’re most likely in your tap water. A water report from your municipality or a water test report from a lab can confirm this.
Sure, you still add Cal-Mag + and Primary nutrients to supplement what’s in the water but the micros most likely come pro bono with tap.
