Laravel custom validation message for multiple fields with the same name

Question

I have the following validation in the controller's action:

foreach ($request['qtys'] as $key => $val){
            if (!$this->_validateMinQty($key, $job, $val)){
                $customerTitle = $job->customers()->where('customer_id',$key)->first()->title;
                return redirect()->back()->withErrors(['qtys' => __('The qty of the customer :customerTitle is less than allowed qty',['customerTitle' => $customerTitle])]);
            }
        }

This check multiple form's input named qtys in the view:

@foreach($job->customers as $customer)

    <div class="form-group {{$errors->first('qtys has-error')}}">
        {!! Form::label('qtys-'.$customer->id, __('Qty').' '.$customer->title) !!}
        <div class="row">
            <div class="col-md-9">
                {!! Form::text('qtys['.$customer->id.']',$customer->pivot->e_production,['class' =>'form-control qtys', "data-sumequal"=>"qty",'required' => 'required','title' => $customer->pivot->aid,'id' => 'qtys-'.$customer->id]) !!}
                <div class="help-block with-errors"></div>
                 @php ($eleE =  $errors->first('qtys'))
                @include('layouts.form-ele-error')
            </div>
            <div class="col-md-3">
                <a href="/storage/create/{{$customer->pivot->aid}}" class="btn btn-nile"><i class="fox-add"></i>{{__('Add Storage')}}</a>
            </div>
        </div>

    </div>
    @endforeach

The above code works, but with the following limitation:

The error message is rendered under every input named qtys[x] where x is an integer and the first input only Testana has the invalid qty, like the following screen shot:

In the controller's action return message, I have tried to use indexed name for the input like the following:

return redirect()->back()->withErrors(['qtys.10' => ....

However, it prevents rendering the error message under any qtys field. Is there any solution?

The solution that I have found starts from the definition of first method found in the view :

@php ($eleE =  $errors->first('qtys'))

This, in my code, should be changed to:

@php ($eleE =  $errors->first('qtys.'.$customer->id))

Because the multiple fields have gotten keys equals to the customer id. This is a technique I usually use, when I want to send double piece of data in single post or in single form element. Then in the controller, I keep the first try,

return redirect()->back()->withErrors(['qtys.'.$key => __('The qty of the customer :customerTitle is less than allowed qty',['customerTitle' => $customerTitle])]);

Where $key is an integer.
