A picture would help a lot to guage pot vs. plant size (have you taken it out of the pot to see if it's rootbound?). Yellowing does usually mean it's getting watered too often, but not knowing in fact how hot it is indoors (115?) it's hard to judge the relative balance. I hope it's nowhere near an airconditioner, because that can cause trouble too. Don't be afraid of sun INdoors, unless it's really baking right against the glass, a pom. shouldn't mind that much at all and could suffer from not enough depending on how many hours it gets daily. I also hope you're watering from above and not by immersion, and that the soil down into the pot isn't soggy wet from the previous watering (just moist is better, and dry on top.

Hi Lucy, Thanks for your answer! I don't see how to post a photo - could you tell me how?

As of today it's improving - quite a few new buds and leaves, counted at least 16 that bursted out between this morning and midnight - pretty exciting bc it looked dire a few days ago!

I've always watered from top - never left soggy. Temperature has been between 72-80 F, maybe a tad more due to faulty ac..

After posting the initial message I added a second platter with water below (under the drainage tray) for humidity - appears it may be helping..

Just checked the bottom of the pot and noticed that there is indeed one root poking out now (wasn't there 6 weeks ago). Should I repot? Or would that be too stressful now?
