The EC is coming out lower than the input. But here's where it gets confusing because the green healthy plants it's going in at 1.0 EC and coming out at 0.5 EC. And the bigger plant with the problems is going in at 1.3 EC and coming out at 1.0 ECIt never hurts to do a runoff check now and then, record EC and ph of the input and runoff solutions.
