It's a little hard to understand this when there is dwc going around and roots in nothing BUT water. I try to let my soil get nice and dry before watering again, however sometimes you don't get to do that and it will still be wet somewhere around the lower half area if you can see through the pot you can tell. I've had root rot but that was from shitty soil that never dried, you use a fast draining soil and root rot is almost impossible.

Also, lights killing roots I think is false. I have lights hitting some of my tomato plants roots and they are doing just fine, the light just supposedly helps fungus or whatever grow that competes with roots if light can hit there.

DWC, Turbo Trays, Bubble Buckets all work because there is alot of oxygen in the water.  When you are using soil/less substrate and over water the roots are not receiving proper O2 and the plant becomes ill.
Light is bad for roots.  You explained it to yourself :-)
When we take a plant, animal, fungus or other living thing and try to improve it's nutrition and growing environment to accomplish the best results possible; we are emulating mother nature, not changing her ways.  You just can not fight nature and win.  Marijuana roots are meant to be subterranean which is dark, hence no defense mechanisms for certain molds and bacterium that thrive in an environment with light present.
I would be interested to see OPs babies again.  Did they pull through OP?
I myself just started 6 seeds of a strain we are calling "Mellow Passion"
(LA Confidential x Trainwreck).
Good luck OP :-)

Roots + Light = Bad

End of story.

If you get .69grms/watt with light hitting roots you should get .8+gms/watt no light to roots.
