Your babies look happy and healthy.
I'm taking bets on which one I'm going to kill first...

You've got your PH issue figured out now, so you'll be fine.
Keep in mind that the plants growing in perlite and/or coco are soil less and use the Hydroponics PH chart.
The weird difference between the two charts, is that in hydroponics, calcium is locked out above 5.8 and in soil, calcium is locked out below 6.5
Keep an eye out for calcium deficiencies and excesses.
I'm not sure if adding potting soil or compost to coco or perlite means that you're growing in soil?

Thank you!
That is really useful! Latest test is .75g of citric acid to a 4.5 litre demijohn of my tap-water gives 5.81 pH after 24 hours. So that would be bang on for plants in pure perlite/coco. Will continue messing around with compost mixes, but also now minded to attempt to rescue some plants by trying the same root-wash that worked on the C6, and getting them rooting in pure perlite (or perlite/coco) - then I can take cuttings.
Keep in mind some nutes lower the ph as well. Some concentrated ones lower it enaugh so you don't need extra ph down. So even if you found the mix to get that ph, you should still check it again after you mix your nutes at the final concentration. I personally do the ph correcting last.
Good luck fixing it. For me it seems the problems are behind by now, so I hope you find at least a good degree of success, even if you can't totally save them by now.

My degassed tap water is PH 7.20 and drops to 6.36 after I mix in my nutes.
Compost can change the PH as well but it's hard to monitor because it happens in the soil after you water the plant.
Checking your runoff PH can give you an idea of what may be going on in the soil.

You can test your compost mix by taking a sample then stir in distilled water to create a slurry and test the PH of the slurry.

Might keep some of the new batch just in coir/perlite, and give liquid feed. Would be a fun experiment. I've not totally given up on the older plants, but they are not gonna win any beautiful baby competitions any time soon. Low effort attempt to save some of the genetics - wash all the roots clean like I did with C6, and then plant into larger tubs of perlite, multiple plants to each tub - almost as if they were cuttings. Might even be able to get them all in 1. Will be easy to water/feed. If any revive, then I can repot them.

Depending on whether or not I manage to save any of the earlier batch, I might pop some more seeds. As the title was "White Rhino & Friends", I should include the other White Rhino crosses I made -
This has been an embarrassing grow, but an educational one!
- Dance world x White Rhino
- Johaar#3 x White Rhino.

Gave the new babies some 1/4 strength tomato feed yesterday, with a little maxicrop seaweed extract. Water pH'd to 5.8. Maybe too soon, but they were starting to look a bit yellow.

I know they can be a sign of overwatering, but I'm generally happy to see mushrooms in my compost - if there are mushrooms, there are mycelium in the soil, which is a good thing.
