WT and DB, I can't keep up with you guys. I'm gone for a couple of weeks, and the entire Star Wars trilogies are nearly reproduced here. I'm sorry I can't add anything to the advice being given for your mom plants. I would tend to agree they may be rootbound, and I've read trimming the roots is a viable solution. A good flush may do the trick too, although it seems like you said you have not given them any nutes? Flushing couldn't hurt though.

I know you will get their problems sorted though - you've got the thumbs for it! Take good care out there, my friend! Good luck!
