My Grobo has an issue with the PH sensor and dosed the plant down to a PH of 2.25. I’m lucky to have caught it quickly, removed the PH bottles and have been managing it myself and I am happy to report that the plant has come back to life. My question is, should I cut off the burnt leaves?

Send a ticket to @Stephen /calibrate as quickly as possible.
I think I would cut the burn leaves, it looks like significant damage, but I’m sure more knowledgeable growers will chime in soon.
Good luck brotha

The bottom-most set with most damage can probably be cut off. I personally wouldn’t cut the others quite yet until more grows in.
Usually would wait until I see them “perking up” again before cutting as well. But it probably wouldn’t hurt if you didn’t wait.
