Hi all, I've had two mass canes (same pot) for about 5 years. I re-potted once and had no other issues. About 6 weeks ago the leaves on both were green but droopy so I took the plants to another apartment. They did OK but leaves were still droopy. After a few weeks I re-potted both. They were pretty pot-bound and I had to untangle roots to separate the plants. I planted each in its own new pot with new Miracle-Gro indoor plant potting mix. I did lose some small roots on both plants but overall system looked OK if a little damp. I then watered thoroughly. Each of the pots has 4 drain holes. Unfortunately the plants are both declining (the tall one much more than the small one). Photos 1 and 2 are from 10/11/2020 the day after re-potting and the rest from 10/26/2020. That's a pretty fast decline. I think they are getting good sunlight that isn't direct, no strong air currents, and the temperature is always in the low to mid 70s. It's been in the low 70s outside so I don't think it's the window and the plants have always been near windows. I live in a humid area so that's not an issue. I can't tell if my plants are overwatered, underwatered, or diseased. Signs of underwatering: I have always always thoroughly watered every 2 weeks. This time I haven't watered for just over 2 weeks due to my concerns for over-watering. Signs: wavy leaves (improving), noticed dirt pulling away from edges of pot, soil feels mostly dry if I stick my entire index finger all the way down. Signs of overwatering: brown leaf tips that I since cut, presence of fungus gnats which is new since the re-pot (although declining in number since I stopped watering), never saw water pool below the pot after watering thoroughly after repotting despite the 4 drain holes I made. Signs of possible disease: some leaves on the big plant got little patchy brown areas or sometimes brown spots circled by yellow. I got rid of a lot of dead or diseased leaves and cut away some brown areas but more keep coming. Mostly affecting older bottom leaves on both plants but some newer leaves on the tall one as well. I just sprayed those areas with a mix of distilled water with a little mineral oil and baking soda because I read that could work for fungus. So - please help tell me what to do next since nothing seems to be working. I don't want to over/under water if my problem is the opposite thing. I also plan on watering with distilled water instead of sink water from now on. I don't want to kill these plants I've had for so long. Note: the small one is actually a shoot from what used to be a second taller one that died off maybe two years ago.
