Django form looping closing tag

i'm trying to submit more than one form with one button using this as an example.

The difference is that i'm adding forms dynamically using this code:

{% load crispy_forms_tags %}
<form method="POST" action="{% url 'App:Submit' %}">
    {% csrf_token %}
    {% for form in forms %}
    <h3>Hour {{ form.Hour }}: </h3>
    <form>
        {% csrf_token %}
        {{ form|crispy }}
    </form>
    <br>
    {% endfor %}
    <br>
    <div class="col text-center">
        <button class="btn btn-primary" type="submit">Send</button>
    </div>
</form>

Using this example, in Chrome, the main <form> tag with the action closes after the first loop.

Any idea why this is happening? Thanks
