I do not follow the apps watering schedule. Just use it as a guide. I’m curious about its timing though and wonder if anyone has any thoughts on it. I have many Hoyas and I can’t figure out why the watering schedule can be anywhere from 11 days to 16. Similar size Hoya, same 3” pot, same lighting. Are some Hoyas known to be thirstier? It makes sense, but all mine seem to average about 12 or 13 days.
