The Grobo does monitor humidity, temperature, and possibly water temp (Not 100% on that last one) but the data isn’t available to us. They do not notify you as of yet when these are at a dangerous range for Cannabis health (But there are plans to add notifications soon)
Since Grobo said everything looked okay, it’s hard to pinpoint what the problem might be and I would imagine they looked at all the data including the above mentioned indicators. How much of your Bottle #1 and Bottle #2 are used to this point? I wonder if the pH probe isn’t calibrated right but looks okay on Grobo’s end, but in reality it’s not right?? Idk.
Tap water can be risky because although the pH might be okay, that doesn’t mean there couldn’t be harmful metals or other chemicals like chlorine at high levels etc in your water… some places in the US have better water than others, but tbh all of it is pretty bad in 2020. That could be hurting your plant. It’s not recommended for that reason.
I agree with pushing the pod up a bit if it seems too wet, however, I would be scared of crushing the roots, as you can see they are popping out the sides near where the pod would be pushed up and might break them? I have this problem currently too so Idk the right answer for it. Your pod doesn’t look too oversaturated from the pic and the stalk looks fine to me at the moment… my last grow however, it seemed like the pod stayed wet for like 3 weeks so I had to move it up and use paper towels to get it to dry out, I had a blemish on my stalk that could have been caused by it, not sure though.
I want to believe that if you slide the pod up carefully the roots will just push in and will slide up with the pod, but it scares me. My taproot currently looks like this, and I really want to move the pod up a little further but I’m too worried ill break the root off.
