Browning of center of leaves: Optimara Tradition.
I had an Optimara Tradition which developed brown spots on the leaves and eventually I tossed. I rooted a healthy leaf from it and it produced a few babies which I have been nurturing. These babies have started getting brown discoloration as well. I don't want to lose the babies too!
Is there something I can do here? Are they getting too much light? (Currently under a single bulb, a "Jump Start Grow Light" 24 watt T5 6400k fluorescent bulb). Plants are about 8-9 inches from the light.
The plants are small so it's difficult to get pictures of, and the flash doesn't help with all the shininess, but here's what I have. The smaller baby is still being kept in a clamshell type container for humidity, #2 isn't.
You can see the browning especially on the smaller leaf, center.
The original plant, when I first saw the problem, although the babies browning is a little different:
I'm not sure what to make of this. Anyone have any suggestions? Thanks!
