Thanks for the help Weedhound. I was thinking it was possibly over-watering, since I put it on the same water schedule as the big one, and it's probably not sucking up as much water.

The soil is MG 3-month or whatever it's called. It might be a little hot (as people have said about MG), but she's way past her seedling stage, so hopefully she will survive and overcome.

I will check out the Rhizotonic for sure.

Thanks!

Any other opinions out there?
