Their team put some OT hours in to monitor my grobo for 2 days and concluded that the unit is not functioning according to software logic.
They are serious about being successful. I’m bought in for sure.

Late Vegetation (Day 4 / 14)
My new unit should arrive tomorrow and I was getting tired constantly checking my PH so I found this aquarium ph controller on craigslist for $60. It works great and I am so glad to have an accurate reading. Next up, look for EC monitor. I am also planning on getting a wireless hygrometer so I can just monitor everything from outside the grobo.
Also did some lst today. Will have to undo and rotate tomorrow when I transplant to new unit. Planning on pruning the yellow leaves off after the transplant is a success.

That’s pretty awesome, I definitely can use that with IFTT and SmartThings or Alexa to automate the environment conditions. Going to add that to my wishlist, thanks SWSVIC!

New Grow Journal - MK Ultra (Generic Hybrid Recipe) - Transferred to a new grobo unit
Late Vegetation (Day 1 / 8)
I pruned her early this morning and transferred her into the new grobo that arrived. So glad its dent free! I also noticed that the window tint is now blue and its much harder to see inside the grobo through the fluid glass.
When I filled her this time, I did not PH the water to allow the grobo PH it and verify its working. The grobo took the PH down to 6.1 then it climbed back up to 6.4 and now sitting between 6.2-6.3. I only used 5ml of hydroguard with my fill only this time around.
After setting up the chiller, calibrated my grobo probes, and added an extra airstone, I transplanted MK over to the new grobo and tied her back down.
I also saw this PH drift problem/solution chart on a thctalk forum and thought it was pretty useful and helped me understand PH drift more.

Thanks, she bounced back after 1 day of transplanting and been going strong since. I am loving the new grobo replacement, everything is working perfectly.
Here is the links where I got that chart from:

Late Vegetation (Day 5 / 15)
She’s starting to get pretty bushy and responding well to all the LST shes gone through.
I’m planning on putting on a scrog and do some pruning this Friday.

I found one of these suckers in the grobo today and took it out. Anyone know what it is? Looks like a fruit fly but I’m not sure. Ordered some neem oil just in case

Use sticky traps to try and remedy the issue first. I found some single sided ones that I affixed to the grobo walls using small magnets. This will aid you in monitoring the issue so you can better determine if it’s isolated or if it’s infested prior to taking more dramatic steps toward remediation.

Keeping an eye on it, so far its just 1, I’ll add a DIY fruit fly trap in there (small bottle with dish soap and vinegar) just in case. Actually I’ll leave it out side the gobo, dont want to attract more inside of the grobo lol
also just purchased the sticky paper, thanks

Installed the scrog, hoping to use this to slow down the more dominant branches so the rest can catch up.

As I’m working to manage the dominant branches and bending them so the smaller branches can catch up, it reminds me of the song Rush the Trees
I am planning on extending late veg for another week after my nute change tomorrow.
Tie down part 2.
