This is my favorite plant and for the most part it’s been doing well. I know these are hardy plants because in a lot of places they’re considered weeds and have very tangly roots. I started these guys by seed earlier this spring and they’ve gotten crazy ever since!  I water it every-time the top two or three inches feel dry. I also repotted recently out of its nursery pot into a terracotta pot and inch bigger, I’d say maybe 3-4 weeks ago (I seen that the roots like to be snug, I may be wrong) within the past day or two it started shedding some of the lower leaves and it’s starting to look a bit leggy. Would a grow light help it grow some of the bottom leaves back? I was also wondering at the top of my tallest branch if those buds forming by the new leaves are flower buds waiting to form? I just don’t want to do anything to stress it out too much or make it unhappy because it’s doing fairly well right now besides that! (First pic is a day or two before I noticed some of the leaves turning yellow, and the second is after. Today most of the yellowing leaves dropped so I went ahead and trimmed off the rest of the stem left over) another issue im having is supporting those tall branches! What could I get to support them but also not overcrowd the pot too much.

Sensitive plant help!
