Parents / siblings / children: struggling to select relevant element

I'm creating a blog and am trying to toggle an edit comments form using JQuery.

Here's the full code for the comments display section:

<!--================== COMMENTS DISPLAY SECTION     ====================================================================-->
<div id="comments">
    <% blog.comments.forEach(function(comment){ %>
    <div class="jumbotron comment">
        <div class="row">
            <div class="col-md-1">
                <img class="comment-ico" src = "<%=comment.author.image%>">
            </div>

            <div class="col-md-7">
                <h4><%=comment.author.username%></h4>
            </div>
            <div class="col-md-4 date">
                 <%= comment.created.toDateString()%>
            </div>
        </div>
    </div>
        <div><p><%=comment.text%></p></div>

<!--=================EDIT COMMENT FORM =========================================================================-->
   <form class="edit-comment-form" action = "/blogs/<%= blog._id %>/comments" method = "POST" id="newComment">
        <textarea class = "form-control" rows="4" placeholder = "Type comment here..." name = "comment[text]"></textarea>
        <button class = "btn btn-lg btn-primary btn-block">Submit</button>
    </form>
<!--    ==================================================================================================================-->
<!--=================COMMENT OPTIONS (visible if user = author) =====================================================-->

    <% if(currentUser && currentUser.username == comment.author.username) { %>
        <div class="row">
            <div class="col-md-1 choice">
                <a class="edit">Edit</a>
            </div>
            <div class="col-md-1">
                <form id = "delete-form" action = "/blogs/<%= blog._id %>/comments/<%=comment._id%>?_method=DELETE" method = "POST">
                <input type = "submit" class = "button-delete" value = "Delete"></form>
            </div>
        </div>
    <% } %>
    <hr class = "style-three">
    <% }) %>
</div>
</div>
<!--====================================================================================================================-->
<!--======================ADD COMMENT FORM ================================================================================    -->
<% if(currentUser){ %>
<div class = "container form">
   <form action = "/blogs/<%= blog._id %>/comments" method = "POST"  id="newComment">
    <div class="row">
        <div class="col-md-2">
            <img class="newComment-ico" src = "<%=currentUser.image%>">
        </div>
        <div class="col-md-10">
            <label for="comment">Add comment</label>
        </div>
    </div>
        <textarea class = "form-control" rows="4" placeholder = "Type comment here..." name = "comment[text]"></textarea>
        <button class = "btn btn-lg btn-primary btn-block">Submit</button>
    </form>
</div>

<% } %>

My JS is as follows:

$('#comments').on('click', '.edit', function(){
$(this).parents().siblings('.edit-comment-form').toggle();
})

However, this is selecting ALL dynamically displayed items (comments) so that when I click on the '.edit' element, all comments reveal their edit box. I know this is to do with how I am selecting them in terms of parent/sibling etc. but cannot work out what it should be!

Solution

@Satpal comment is perfect and credits to him, with his mercy though, I'll try to dive a bit deeper into the logics:

$('#comments').on('click', '.edit', function() {
    $(this).closest('.row').prev('.edit-comment-form').toggle();
});

Since .edit is inside of .row and .edit-comment-form before it (.row), basically you are impacting the previous .edit-comment-form of the closest .row's clicked .edit.

On simpler words, the closest row is the same as the clicked edit and it's previous textarea (.edit-comment-form) will be toggled.

Here's a generic example of both prev() & closest() jQuery methods:

Also notes why find() didn't work, because it toggles all .edit-comment-form nested in #comments.

var selected = $("#start");
selected.css("background", "gainsboro");

//prev() - Will select previous element disregarding tag name
$(".prev").on('click', function() {
  selected = selected.prev();
  $("div").css("background", "");
  $("nav").css("background", "");
  $("section").css("background", "");
  $("span").css("background", "")
  selected.css("background", "gainsboro");
});

//closest() - Will highlight red only if selected element is a div
$(".closest").on('click', function() {
  selected.closest('div').css("background", "red");
});

//find() - Will only highlight when span element is child 
$(".find").on('click', function() {
  selected.find('span').css("background", "red");
});

//Reset
$(".reset").on('click', function() {
  $("div").css("background", "");
  $("nav").css("background", "");
  $("section").css("background", "");
  $("span").css("background", "");
  selected = $("#start");
  selected.css("background", "gainsboro");
});

div {
  width: 40px;
  height: 40px;
  margin: 10px;
  float: left;
  border: 2px lightgray solid;
  padding: 2px;
}

.inline {
  float: left;
  margin: 10px;
  width: 48px;
  text-align: center;
  line-height: 48px;
}

#row {
  width: 100%;
  border: none;
  padding: 0;
  margin: 0;
  height: 60px;
}

section {
  width: 40px;
  height: 40px;
  margin: 10px;
  float: left;
  border: 2px lightgray solid;
  padding: 2px;
}

nav {
  width: 40px;
  height: 40px;
  margin: 10px;
  float: left;
  border: 2px lightgray solid;
  padding: 2px;
}

span {
  font-size: 14px;
  word-wrap: break-word;
}

button {
  margin: 10px;
  padding: 10px;
  background: transparent;
  border: 2px solid gray;
  border-radius: 3px;
  color: gray;
  font-size: 12px;
}

button:hover {
  background: gray;
  color: white;
}
