Hey everyone!

I'm new to the forum, but not totally new to AVs. I have helped my mom take care of her's, but I'm getting married and moving so I ordered some of my own from The Violet Barn. I have my AVs, Streptocarpus, and my Kohleria in two windows, same wall, same room. Everything is growing well except my Ma's Mei Lee Strep. It's not growing...it's not dying! It's supposed to receive the same treatment as AVs and be a faster grower, but nothing. It's healthy green, a bit droopy, but no new growth since I bought it almost three weeks ago. My other streps have stolons and/or are already in bloom. Have any ideas? I started Streps because of how beautiful Mei Lee was and it won't grow! :(
