I have seen and had all of those symptoms you are showing. Unfortunately I wasn't scientific about the cure, so many things could be wrong. In fact I think many things are wrong.

When I got the spots as shown, I suspected a root fungus or heavy nutrient/PH burn. If this is the case, we destroyed the roots and it will take quite some time to repair. If so, foliage feeding is our best shot. If the clones have heavy root damage, it could be as long as a month before they are back. The ones that don't die that is.

You let your clones dry out? Not me.

Those grow bags are convenient, but I would worry about root damage from moving them. For that reason, I prefer cheap rigid plastic pots. That way, root damage is minimized when moved/turned.

Dry? They look dry too. If you are worried about root rot, mist the tops of the soil to prevent drying. In fact, a slightly moist surface will help keep things flowing by "Wicking" the excess moisture up, and allowing water to penetrate down when you do water.

You listed PH for your tap and runoff. What was your Nutrient solution PH? Did I miss something? I have experienced a huge swings in PH using organic ferts. Foxfarm, which I am using now, may be part of the problem as well. Makes me think something is out of whack with their consistency.

That Alaska stuff you are using doesn't have any nitrogen. Even with good soil you should consider a fert with some nitrogen even during the bloom phase. It also may be void of other needed nutrients.

Although your posted temps seem fine to me, I wouldn't be surprised if there was a heat issue. Ambient room temps are lower than what the plants experience directly under the light. Also if there is a root problem then they may just not be soaking up enough water even if the temps are OK.

MY FIX
Is the same no matter what the problem is.

Spray/mist with
1 qt water
1/4 tsp hydrofarm grow
1/4 tsp hydrofarm bloom
1/4-1/2 tsp hydrofarm micronutients

The micro has some calcium (A big issue with tap water), but using a 1/4 tsp of Botanicare CAL-Mag may help too.

Sure the above aren't technically organic but they are all derived from natural sources and purified in a lab. You also want something that will be taken up quickly since you are fixing a problem
mendokid Reviewed by mendokid on . Prepared for the worst- Stinky?? I'm just about to give up...... My last grow ended in disaster. By the time I got the fungus gnat infestation under control, my stock had been destroyed. I assume it was a fungus; the leaves spotting, yellowing and dying and the roots, at finish, were brown and withered, not mushy. The cuttings I took from those plants all failed, all 80 of them, every one the same, curled tips and yellowed leaves. There was something that smelled in those domes that I had never smelled before.
