The plants height is normal and desirable as Athos stated. It is better to have a shorter plant with little spacing in between internodes rather than a plant that is large with few internodes. The internodes are the areas that the buds/flower develop.the more internodes you get the more bud production that you get. Your plant appears very healthy and I wouldn’t worry myself too much. Your day temperature is a little high however and if at all possible try to get it down to below 80. Hope this helps and good luck on your grow!
