The symptoms I observe is, stems going purple, very short stumpy new growth with lots of side branching.
This is read as stress from my end, seems to be attempting to create more shade for itself.
This is confirmed for me as I have twice tried to run all light on, which results in above observations.
To be honest I corrected the issue with Epsom salt and less light, and above update does unfortunately only flex the healthy part.
Should have documented the stress response and how I corrected it as it may help future readers.
Will be sure to document it this time as I'm about to start running all light again, just needed plant to recover al look 100%
