Are they all the same strain too?

You could be dealing with plytherwilt. It's common in Rockwool, there is an art to growing with it.

What is your water schedule again...I'm sure you answered somewhere but this great thread is to large to read. I just don't have that much time this month. (not that your post is that long) I just have a new project that is taking all my time right now.

I will stop back tomorrow AM and see if I can offer you any advice. The CalMag Plus was a good thing to add.
Zandor,

Thanks for taking time to reply, as I know you have been a busy man lately. To answer you questions:

1. The rockwool does not smell.
2. All White Widow Clones
3. The watering schedule is at 10:30AM and 4:20PM for five minutes each.

I too think the CalMag was a good thing to add (thanks for the heads up on that) becaue it eliminated one more possible cause of my problem which then allowed me to find the probable problem which is something with the roots. Thanks for everything.
