Nutrients didn't dispense after lasts water change

I noticed the nutrients didn’t dispense after my last water change a couple of days ago. Is there any way for you to check this on your end?

pH 6.4
water temp 67
air temp 76
Humidity 39 (working on getting this up)

Thanks for your help!


How long have your current grow been running? What kind of water are you using? are you using any additives? this happens to me when my water ppm is too high when filling the grobo.

This also can happen when the EC sensors have buildup on it and may need to be cleaned.

I would submit a support ticket:
