I take it outdoors during good weather and bring in the winter. This last year I repotted into larger pot and it really took off in growth and is about 4 feet tall and two nice leafy branches. Now indoors and the bottom leaves are turning yellow along the vein lines and drooping. I researched and found it has a running canker so I’ll scrape it off (about 2/3 up on trunk). I take it outside and water thoroughly and allow it to drain on warmer sunny times of day and return to indoor sunny window location. Sometimes it is leaf drooping before the end of the week and I’ve added sparingly water to avoid ruining the floor with drainage. It seems to be in maintain mode - the new leaf isn’t growing, nor is it dying. I’m concerned to keep it happy and healthy and haven’t found good info online to care for it that way. Any suggestions are welcomed by both of us!

it may have remained too wet for too long at some point. It appears to have an infection. You can try putting wettable sulfur and dolomitic lime in for the next time you water, and this can help kill off the infection. They really need more light than inside a house can give them. You might want to invest in a horticultural fixture of at least 100 watts.
