The plants look good.
There doesn't seem to be an excess or deficiency of nutrients.
You should let the substrate be "dry" between waterings. "Weigh" the pots with both hands and notice that it's light and that "the bottom doesn't feel heavy." If you notice weight at the bottom, it means it still has enough moisture.
Water only when it's "dry."
Additional tip: Always alternate between a watering with water and a watering with nutrients. In both cases, with adjusted pH.
