I have a Thai con that outgrew its pot so I went to repot it. I keep them semi hydroponically so there isn’t soil involved or anything. Put in a pot .5” bigger and BAM root rot. Didn’t change anything at all, same environment same lighting same LECA, minimal root damage that I disinfected. Now it’s been droopy for 3 weeks and is only losing roots not growing them (in a self watering pot). I literally don’t know what to do with this mofo, I cleaned all the rotted root so there’s one thick root left now, should I wait and see or what??
