Black Spots Appeared Overnight

Firstly; breathe. Take a step back and stop doing things. Secondly, your pH should be closer to 6.5, and if it were me, despite the averages, I'd be sure I was floating in that area (pH 6.5). Thirdly, you took these plants from synthetic feed, to flushing and no feed, to new organic feed (top dressed)...all in the course of a few weeks. Your plants don't know if they're coming or going. Fourth, yes, even though your organic amendments may not be available to your plants right away, the addition of them into your soil will surely alter pH in a much shorter time.

So you've committed to the organic / dry amendment route, so let's stick to it...no, don't consider quitting this run. You won't learn diddly do otherwise. If this were my grow, I'd foliar spray some Epsom salt...it will help your plants with their Mg issues while not muddying up your soil any more than it's been. You should see results in a week or so, depending on your plants. I would manage your pH a bit more closely and I'd refrain from doing anything else...no flush, no new amendments, no fancy this or that. Commit to your cause (growing in soil) and take as many notes as you can so you don't run down this rabbit hole again. Be patient...
Thank you so much. This is the answer I was looking for. I’ll add a little sulfur to drop the ph a bit, and water only for a sec. Thank you.

The plants seem to still be getting worse. They are losing more and more leaves and some plants only have 3 leaves per stem remaining. Could it be root rot? And if it was root rot, would the root rot spread across all my plants at the same time, or would it be individual plants that would get sick? I’m asking because all my plants seem to be affected at the same time. If root rot can’t be spread pot to pot, I think it’s probably the amendments I put in that threw it off.

I would say unless all the plants are in the same pot, reservoir, etc, that you're not going to get root rot to transfer from plant to plant...even if it does, because I don't know that it would. Remember, patience is waiting more than 3 days.

Have you sorted your pH?
Have you sprayed the Epsom?
When did you water the last (3) times?

I sprayed Epsom, I’m about to water it again today, I watered it two day’s ago too. Should I change the soil ph by watering in at 6.2, or should I change the ph by adding sulfur?
