Laravel like in where don't return result if space exist before character

I don’t know how to explain more my question; on laravel I need to return members has code start with (J or j) but when I use ('members.code', 'like', 'j%');

there are some members in var_dump of code are like " J3X", " jh4", " j5T". my code is returning only those who are like "jH6"; "J9u" … but not if they have space or more than one sapce in my result.

I want to return all members that they have code start with j even there is space or more than one space in code.

my query is

$query = member::where('members.inscription', '>=', $date_start->startOfDay())
                ->where('members.inscription', '<=', $date_end->endOfDay())
                ->where('members.id_member', '>', 1099)
                ->where('members.code', 'like', 'J%')
                ->orderBy('members.id_member', 'DESC');

$members = $query->get();

var_dump($members); die;

$query = member::where('members.inscription', '>=', $date_start->startOfDay())
    ->where('members.inscription', '<=', $date_end->endOfDay())
    ->where('members.id_member', '>', 1099)
    ->whereRaw("LTRIM(members.code) LIKE 'J%' OR LTRIM(members.code) LIKE 'j%'")
    ->orderBy('members.id_member', 'DESC');
