I have an idea but i already think everyone knows what im going to say...did you increase light as well.Theyre legit dormant. Nothing is happening. Not dieing, not growing, def no tissue necrosis. But they look bad. I can confidently say the tips have continued to "slightly" grow, but not like the growth I had, nor the rest of my system.
Whats bizzare is they were full PE up until the day i chopped it. I think it was a $75 colony and I was able to trade out frags to cover cost - but i thought it was a neat piece and with all of the luck early on I had no intention of chopping it but couldnt get the STN to stop. My expectations were low from the rip.
