kctats13,
rather than waiting on your PF meter to get there, go to a pet store and get a drop kit with a range from at least 6.0 for the bottom or even better 5.5 and use it until your meter arrives. While 5.8 maybe better, 6.0 will work too.
Unless you need the cloner for something else put them back in and let them either grow or die. You were correct that your biggest problem was cold temperatures. The people that I deal with recommend temps in the high 70s.
I pulled 3 out of 20 through that has been too cold just by leaving them alone after I got the temps back up and stable around 80 to 82F.
If they are looking like they are beginning to root, just leave them a lone. If you are going to recut them, then move up as close to the next node as practical, use you rooting hormone and start over. If you have enough stem left to recut them and start over, that might be the best thing to do. I've never tried recutting because I just leave them until they die before I give up.
They look healthy enough that I might try recutting them. If you have more than one from each mother, you might try leaving one alone and recutting another one. That way your chances of doing the right thing have doubled.
Good smoking.
