I'm not sure what would cause that. The leaves on my sour cream are curling inward. The new leaves on the bubble don't grow straight out they twist but they end up growing correct. I think it's from all the compact growth it's the only direction the can go for a while. Both of my plants are very bushy, although the sour cream is super compact and the nodes are way close to each other, whereas the bubble is a little more spaced out. It's still 6" tall. It'll probably be 7" by Monday. Hopefully the sour will be 6" by then. It's 4.5 now.
napa, what would the pH have to be? slightly too acidic or too alkaline?
