Dwarf / first grow

Your plants are looking very tight in the grow room, lack of airflow in flower can be detrimental and cause issues "molds and mildews" in the long run, keeps up the air movement to prevent some of these things. Your plants are also looking a bit wited in the leaves this could be to much water or not enough or high temps with RH. Check the leaf stem by pressing/bending it with your finger. Limp Leaves + Stiff Stems = Overwatered Limp Leaves + Limp Stems = Underwatered Other wise they are healthy looking, just outgrew their space and the lights maybe a bit under powered for the task at hand. Take notes and try and improve it all for next grow. Look into LST and HST, topping a plant can be great for controlling height. Good Luck!
