Tell you what, I'll do 'em all. That way we have something to look back on in comparison when I inevitably screw up this grow.
First, I promised the bad as well as the good:

That water in the big tote is the result of running the misters for a week - nutes are kinda wasted. Not exactly, I'll explain. But tonight is maint nite, so those all get emptied, foggers swabbed with a Q tip, and put her back in service. As it is, it's like a hybrid between fog and DWC.
Very petite root structure up top, millions of little hairs. I'll put one under the microscope so you can see better:

And then it becomes rope like in the middle, and standard DWC roots at the bottom since they are sitting in the precipitate.

Those 2 are at the high range of nutes. I ran these ^^^ at 800PPM total.

#2 I ran at 600PPM. #3 was also 600PPM at the end, but I ramped that up from 400. Those 2 plants are now in the other RDWC system living happily. Tote 3 is currently shut down.
Tote 4 was run at 200PPM initially, then ramped up to 400, and by then I was too late. Getting this right when they are young is important. The genetics are still fine for cloning, I was the one who starved them. I could nurse them back, but with the 4 in the back, I only need one mom... I'm thinking just leave them in and see what happens. They were my "Do not go below 300PPM in this system" lesson.
Here's the plants I moved over from Tote 3 to the RDWC system:

I found this very interesting, measuring DO in the res as I topped off with RO, the oxygen went up. I did not expect that. I thought that RO water stored in a 30 Gal plastic tank would be "dead"" of O2. Turns out it is higher than stirring the res with a powerhead and a venturi. This requires further study.

Look at this crazy root. I'm hoping that clones will not have that giant rope in the middle.
