So far the plants are moving along. Today, I added a little more water and checked the pH and ppm. The pH tested at 6.5 and ppm at ~360. I believe the pH is good, but not sure about the ppm. I have also noticed roots starting from all four plants. I was amazed to see how long the roots had gotten this soon.

The first shot shows the root development, and the subsequent photos are in the same order as previous postings. A couple of them still look like there is a problem, due to the coloring. Any suggestions/ideas?

Thanks for reading!
