Growing slow?

So was wondering if my plant growing rate is slow Or not are they suppose to look like this in week 6 of flower? The strain is Sour Diesel just looking at other pics and they week 6 of flower looks completely different.. I know genetics plays a part in it but at least some type of similarities right ?
