Hello! I am seeking advice to help my Thai Constellation! When I got this plant 20 or so days ago it already had half a leaf and all the same sprouts. I have not seen any new growth and I noticed that the bottom small leaf looks a lighter green from when I got it. I replanted it in a tropical soil mix when I got it and 11ish days ago. When I noticed a root outside of the soil had become soft. What steps should I take next to help this plant thrive! It’s about 4 ft from a window and I have a grow light on it 4 hrs in the early morning. Thanks for any help!!
