Cute! I am a new owner (3 weeks) of an F.tea and asked for it because I'd love to see flowers like this.

I am worried that I have overwatered (2-3 days as initial instructions stated, and only when the topsoil and gravel tray are dry). Over a third of the leaves have gone yellow. I've been afraid to go 4-5 days as you suggest, but clearly that's not a bad idea sometimes!

Yeah, even just a bit over a month I can tell you that yellowing leaves are definitely related to overwatering. I also lift the pot to see how light it is, after a few times you can get a pretty good idea when to water. I haven't had yellow leaves at all since the last watering, 4-5 days working quite well for me. 5 more flowers opened already and many more new buds are forming non-stop :)

That's really cool. I let it go 5 days since the last one and will keep it on a 5-day schedule. Hopefully I can correct the damage.
