What are your temps like at lights out?
Your soil looks wet and heavy and if that thermometer is reading 74f with lights on the problem you are suffering is nute lockout due to low root temps. the temp will drop a lot at lights out and won't make it back up again. I'd refrain from trying to repot those plants as the roots will fall apart. try lifting them up off the ground and test temps of the soil. let them run as they are and plant new plants in different pots as those ones will insulate the soil.
Temps at lights out are normal, the thermometer shown in them pictures was at 74 because I had the tent open for a while so a lot of the heat escaped.
I'll see how it goes with the roots. I need to start two new TD if I'm gonna get enough to last me until the following harvest, the AutoX just won't put out enough.
