I got this guy from Peter from Big Leaf. I posted the same pics on his forum but wanted to share it here as well. I've noticed and have since been confirmed that this plant is slow to grow. As you can see a bunch of the leaf surface is white and free of chlorophyll. The newest leaf has been steadily but very slowly growing for a month or two now.
The patterns it makes are awesome. I've noticed some of the roots are white and some are green.
You can see the newest leaf has almost no green! Poor thing. Lol. The hydroton is developing salt build up... Something I need to take care of soon so new and existing roots don't burn.
