All six plants have grown taller than I’d like. So, I’ve pinched them back a bit (removed the new growing tip from each plant), something I learned about when I used to dabble in bonsai. I also raised the light again.
The first photo below shows the plants before starting these procedures. The second and third show a plant before pinching and the same plant after being pinched. The fourth shows the plants put back in place with the light raised.
