When does the first two bottles of nutrients get used, I noticed only very little bit have been used but the other bottles have been used a lot, I’m on late my first day of late veg
Bottle #1 and Bottle #2 are pH up and pH down respectively.
These do not get used often if you use Distilled or Reverse Osmosis water. If you ever notice your machine starting to use a lot more than it is now, you might have a pH probe problem (incorrect calibration)
#3, #4, and #5 get used a set amount on your drain and fill, those are nutrients. #3 and #4 are a mix of Nitrogen Phosphorous and Potassium (NPK) and #5 is Cal/Mag (Calciuim and Magnesium)
Ok cool, thanks man
