Answer 1

this issue appear because one of the value that is between the {{}} returning an array instead of string.
and i think it is in the following code
<input type="text" name="pcorreo" id="pcorreo" class="form-control" value="{{old('correo')}}" placeholder="correo...">
and as I saw in your view code you have an input with name correo[] that is an array, and after the validation failure the controller redirect to the form view, the old('correo') function return an array instead of string
