Current Photos of setup and roots... ( http://imgur.com/a/wmbYZ )

While this is really just for documentation for others so that maybe it might help them... I'm WAAAAY open to some help from anyone who knows more than me... which is probably every single person here.

I've kept the PH correct, Res changed every 10 days, Res temps stay at roughly 72F and I have a good amount of light on the plants 184 watts of CFL's timed 20/4 at about a foot and a half away. Good ventilation as well.

Full timeline Rundown about grow so far...

1. My first grow... (God help us all...)

2. 2 seeds out of 3 germinated.

3. I started in dirt and solo cups with no drainage. The plants got stunted bad with both root rot and complete lack of nuts.... I just had top soil and no ferts. (I fucking know...)

4. I switched to slightly better soil, added coffee grounds, and better drainage as well as a desk top fan to blow over the plants... Plants responded well then got root bound and the drained wasn't good enough, I over watered and once again plants faltered and root rot prob set in again.

5. I finally got my supplies together and switched the grow to the DWC 5 gallon bucket hydroponics that I'd wanted to do from the start. Also added much better lighting and the plants took off like crazy.

6. Buckets got switched out to three high stack of 18-gallon totes with 5 gallon bucket remaining as res.(didn't think I could lift, or manage using the bottom 18 gallon tote as a res.

7. Of the two plants, the taller one showed male so I cut it. However the male's roots had dominated the root zone and entangled with shorter girl. She was pretty weak for a bit and I had trouble getting all the males roots out of the root mass but the female did bounce back.

8. After it bounced back and was growing VERY strongly for three weeks I wanted to try my hand at some more advanced stuff. So I did some aggressive defoliation to make the plant a more bushy. (Removal of almost all upper fan leafs.) At this time also FIM'd and also took 4 clones from the bottom few branches. (They are all doing well btw... sexy white roots in a DIY bubble cloner.)

9. The plant responded really well and exploded with growth from all lower branches filling out the grow space much better.

10. So... after two weeks of rebound growth I figured the plant was ready for another thinning.( T_T ) This time not only did take most light blocking fan leafs, but also FIM most of the canopy level tips. I also let the res go longer without changing (15 days).

11. BAM!!! Crazy root rot, combined with lower leaves showing all kinds of deficiencies.

12. Played it touch and go for a week with two res changes and slightly reduced light level and some misting to try and baby the plant and reduces the upper stress so the plant could focus fighting the infection below. Did a small addition of H2O2 to the res.

13. No luck, rot took heavy control of all of the roots and the plants bottom branches continued to suffer. The root wasn't goopy but rather a slimy mushy kinda root so I figured it wasn't algae.

14. I didn't want to let my first grow end without a fight so I figured I had two paths. I could go for bennies... or try to regain a relatively clean root zone somehow. I looked over all the data and opted for the Clean Path.

15. Two days later I got my new weapon in the fight... SM-90. I gave it a heavy dose of 12ml to the 4.5 gallons that my res is kept at.

16. The SM-90 had the effect of dark brown almost black thin film forming at the edge of the water line and on the net cup. Most of the previously infected thinner roots developing the same film which would come off easily to the touch. Most of the mushy brown roots also now came off easily when slightly pulled at, while the thinker roots remained behind and started showing some signed of whitening. Also at this point a great deal of small bits of roots circulated in the torrent that is my res.

17. FIGHT!!! (lol)​

I drew the conclusion that no mater how clean the roots in the res get.... the roots in the net cup would continue to sit with dead matter around them AND infected hydroton... that would re-spawn the rot. So to the sink I went with a spray bottle of RO'd water, another bottle of H2O2(3%) and my plant. I turned down the lights and every other minute I took time to spray the roots with the RO water to make sure they were never drying out. Over 30 minutes I carefully cut the net cup away, removed the hydroton and pulled everything that was even slightly mushy or decay looking. Then I poured half a bottle of H2O2(3%) over all of the roots, then rinsed with the RO water and pulled at more of the roots to get the last little bit of deadish root away. Then two more H2O2 floods, followed by RO rinses. Lastly I re-net potted the plant with new hydroton, making sure to cut some holes in the net pot and pull most of the root gently through.

Changed the res with nothing but pure RO'd water, cleaned the air lines and air stones. Then dunked the net cup'd plant into the res to get rid of any loose dead roots.(there was still a bit that came off) scooped what I could out and started another bucket of RO water from my RO Unit.

In the mean time the plant will sit in RO water with the air stones on full and 12ml of SM90 added to the 4.5 gallon bucket. In about 12 hours I'll change the res to another pure RO set to get rid of the last bits of floating dead roots. add more SM90 and wait another two days before slowly trying to add back in small amounts of Nuts and CalMag.

Hopefully this has set the "Rot" back more than the "Root" and the plant can out pace the Rot in production of new roots.

Now that you guys know everything... What is my next best course of action... also I'll have some recent pics up a little later...

Sigh.... Help Please.

Remind me never to do a full hydro grow lol.
My heart feels for you brother..
I will stick to soil and perlite :))
Throw em in some soil if possible and start again ???

You may have a point there... hmmm....

I'd do what gixxa said and plant into dirt if you can. For what it's worth, the root crown does look fine to me, I do see the roots you think may have root rot towards the bottom, but honestly I don't think there's root rot? It's hard to tell from the pic, so if they are slimy, smell really bad, pull apart really easily or are mushy, that's definitely root rot. Maybe the gh micro is staining the roots in the water, I've heard that can happen in Dwc.
You'll have to be the judge with that.

If it's not root rot then the pale color of the plant is just from under feeding and I'd suggest upping the Feeds a little, and see how they react over a few days (if you put it back in your Dwc system).

I'm tired af right now so if this doesn't make sense I'll try to explain more later

That's a really small root system for a stem that size. I would say res temps, not enough oxygen (they're correlated) to the roots. Really weird root mass.

Yeah the roots look like string or rope, I've never seen a whole root system look like that before, I've only seen it towards the root crown and the most upper part of the root system. Really strange!

It only has its primary root system all secondary and tertiary branching roots have died off as its growing. Either lack of oxygen, too much heat, or over watering. Those are all very closely connected so that's where I would look for problems.
