Yeah I was wondering if you are trying to clone those in the first photos -- they look a little wimpy but with better light, should grow better once roots are established.
I noticed you are using those root-pruning grow pots. They come as sheets that are rolled into cylinders around the bottom disk piece and secured with the (blue and other colored) buttons, right? I recently came across them in a UK blog and looked for US sources but they are (still?) pretty pricy unless purchased in large bulk units. Have you been using them long? What are your impressions of them?
Noted in the middle photo -- be sure to trim the dead and dying leaves -- I would think especially in a humid hydro set up they can become breeding ground for fungal issues.
Hope to see your progress updates as they grow.
