Looks like a mag deficiency? I only have one grow under my belt so I’m no expert. I encountered cal/ mag issues in my grow and added cal/mag. Someone with a bit more knowledge may be able to assist.

How does your Nute bottles look?
What type of water are you using? Were bottles 1 & 2 used in a previous grow? If not, your system has used a lot of bottles 1 & 2 (pH adjustment). Do you have a hand held pH meter? If so I would test the water in your reservoir ASAP and calibrate your Grobo pH meter as well. pH fluctuations would explain the brown spotting on your plant.

Just came in PH is low very low
There’s your issue.
What type of water? You can’t really measure plain RO or Distilled accurately as they need a buffer to properly register. Also, what is the pH of the water in your reservoir?

The water that you took out pH was 6.5? Or was the new water that you put in 6.5? You mentioned that the pH was low, 6.5 is on the high end.

The PH I took out was 5.5. What is the proper or ideal PH…?? I think I’m going to start pre- treating you make sure the PH is perfect on the next fill.

6.0 is considered ideal. The Grobo should be keeping it there. Do you have calibration solution? A simple calibration of the Grobo pH meter should fix your issue.

Yes I Calibrated the probe 3 days ago. I was waiting on the cal mag, revive, and recharge.
Still waiting on Hydro Guard but my temps are not above 75 for my water they stay at 65.

I would open a support ticket and get the Grobo Team involved. You paid for proper performance, they will make sure you receive it.

6.0 to 7.0 is hydro range as i understand. At 5.5 maybe not taking in nutes. Good
