2 of my plants look like they've stopped growing now and the calcium deficiency looks worse and worse.. should I just flush then with water for a couple of week and be done with them?

What’s up with these plants strange leaf colouration, deformed leaves, thin tips and slow growth? Also what should I do from now? If it’s nitrogen toxicity how can I flush without overwatering? they’ve sorta been flushed But Aren't taking up as much water
