This plant has never thrived and looks sick every other week. I went to bump the pot up a size, but the stem doesn't seem strong enough to tolerate that move. I'm not sure why this plant has failed to thrive, though I think it is more sensitive to cold than the other varieties are growing. No nutrients this week...I'm just letting it live undisturbed these days.
@BioBuds, thanks for the tip! The plants are all on their own schedules, for better or for worse...I check them in the morning and water the ones that are quite dry. It's more important than ever that they dry out now that the temperatures are lower.
